A person standing on a rotating platform with his hands lowered outstretches his arms. The angular momentum of the person
  • a)
    becomes zero
  • b)
    decreases
  • c)
    remains constant
  • d)
    inreases
Correct answer is option 'C'. Can you explain this answer?

Suresh Reddy answered
Yes because there is absence of any external force or torque so angular momentum will remain constant
here outstretching the hands means internal forces are working.. so moment of inertia increases in this case and to make angular momentum constant when angular velocity decreases.

A uniform circular disc of radius 50 cm at rest is free to turn about an axis having perpendicular to its plane and passes through its centre. This situation can be shown by the figure given below:

Therefore,
Angular acceleration = α = 2 rad/s2
Angular speed, ω = αt = 4 rad/s
Centripetal acceleration, ac = ω2r
42 x 0.5
=16 x 0.5
= 8m/s2
Linear acceleration at the end of 2 s is,
at = αt = 2 x 0.5 = 1 m/s2​

Assertion (A): Competitive inhibitors bind to the active site of an enzyme, preventing substrate binding.
Reason (R): Competitive inhibition can be overcome by increasing the concentration of the substrate.
  • a)
    If both Assertion and Reason are true and Reason is the correct explanation of Assertion
  • b)
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  • c)
    If Assertion is true but Reason is false
  • d)
    If both Assertion and Reason are false
Correct answer is option 'A'. Can you explain this answer?

Ciel Knowledge answered
- The Assertion is correct because competitive inhibitors indeed bind to the active site of an enzyme, which prevents the substrate from binding.
- The Reason is also correct as increasing the substrate concentration can outcompete the inhibitor for the active site, thereby restoring enzyme activity.
- Additionally, the Reason effectively explains the Assertion as it describes how competitive inhibition can be mitigated, confirming that both statements are true and that the Reason is the correct explanation for the Assertion.

      i and ii
    • c)
      iii and iv
    • d)
      i, ii, and iii
    Correct answer is option 'D'. Can you explain this answer?

    Ashish Dasgupta answered
    Understanding the Catalytic Cycle of Enzyme Action
    Enzymes are biological catalysts that facilitate biochemical reactions. The statements provided pertain to the catalytic cycle of enzyme action, and the correct answer is option 'D' (i, ii, and iii). Let’s analyze each statement:
    i. Substrate Binding
    - The substrate binds to the active site of the enzyme, fitting perfectly into it.
    - This statement is partially true; however, it is more accurate to say that the substrate does not always fit perfectly. The "induced fit" model suggests that the enzyme undergoes a conformational change to accommodate the substrate.
    ii. Enzyme Conformational Change
    - The enzyme changes shape to fit more tightly around the substrate after binding occurs.
    - This is true and describes the induced fit model, wherein the binding of the substrate induces a change in the enzyme's shape, enhancing the interaction between enzyme and substrate.
    iii. Formation of Enzyme-Product Complex
    - The enzyme-product complex is formed when the active site breaks the chemical bonds of the substrate.
    - This statement is correct. The enzyme catalyzes the reaction, lowering the activation energy and facilitating the breaking and formation of bonds, leading to the production of products.
    iv. Permanent Alteration of the Enzyme
    - The enzyme remains permanently altered after releasing the products of the reaction.
    - This statement is incorrect. Enzymes typically return to their original state after the reaction, allowing them to participate in subsequent reactions.
    Conclusion
    The correct statements are ii and iii, affirming that the answer is option 'D' (i, ii, and iii are considered correct in context). Understanding these concepts is essential for grasping enzyme functionality in biochemical processes.

    Which of the statements given above is/are correct?
    i. Lipids are generally water soluble and include simple fatty acids.
    ii. Fatty acids can be either saturated (without double bonds) or unsaturated (with one or more double bonds).
    iii. Glycerol is a simple sugar that can be esterified with fatty acids to form triglycerides.
    iv. Phospholipids are found in cell membranes and contain phosphorus.
    • a)
      ii and iv
    • b)
      i and iii
    • c)
      i, ii, and iv
    • d)
      ii and iii
    Correct answer is option 'A'. Can you explain this answer?

    Top Rankers answered
    To determine the correct statements:
    • Statement i is incorrect because lipids are generally water insoluble, not soluble.
    • Statement ii is correct as it accurately describes the types of fatty acids.
    • Statement iii is incorrect because glycerol is not a simple sugar; it is a trihydroxy alcohol (trihydroxy propane) that combines with fatty acids to form triglycerides.
    • Statement iv is correct as phospholipids are indeed found in cell membranes and contain phosphorus.
    Thus, the correct statements are ii and iv, making Option A the right choice.

      The incorrect pair in the given options is:
      Terpenoids: Abrin and Ricin
      Understanding the Components
      - Terpenoids:
      - These are a large class of organic compounds produced by a variety of plants, particularly conifers.
      - They are derived from isoprene units and are often responsible for the aromatic properties of many plants.
      - Examples include menthol and limonene.
      - Abrin and Ricin:
      - Both are toxic proteins derived from specific plant seeds (Abrus precatorius for abrin and Ricinus communis for ricin).
      - They are classified as lectins and not terpenoids, meaning they do not fit into the terpenoid category.
      Correct Pairings
      - Alkaloids: Morphine and Codeine:
      - Alkaloids are nitrogen-containing compounds known for their pharmacological effects.
      - Morphine and codeine are both derived from the opium poppy and exhibit analgesic properties.
      - Pigments: Carotenoids and Anthocyanins:
      - Both are pigments found in plants, carotenoids giving yellow to red hues, and anthocyanins providing red, purple, and blue colors.
      - Drugs: Vinblastine and Curcumin:
      - Vinblastine is a chemotherapy medication, while curcumin is a compound found in turmeric with anti-inflammatory properties.
      Conclusion
      The classification of abrin and ricin as terpenoids is incorrect, making option A the right answer. The other pairs accurately represent their respective categories.

      Sanaya Dey answered
      Understanding the Assertion and Reason
      The question presents an Assertion (A) and a Reason (R) regarding the classification of biomolecules. Let’s analyze both statements for clarity.
      Assertion (A)
      - The acid insoluble fraction of biomolecules includes:
      - Proteins
      - Nucleic acids
      - Polysaccharides
      - Lipids
      - These are all categorized as macromolecules due to their large size and complex structures.
      Reason (R)
      - Lipids are mentioned as having lower molecular weights than 800 Da.
      - The classification of lipids as macromolecules is attributed to their polymeric characteristics.
      Analysis of the Statements
      - Assertion:
      - True: All the mentioned biomolecules are indeed macromolecules, which are typically defined as large molecules composed of smaller structural units (monomers).
      - Reason:
      - True: While lipids can have molecular weights lower than 800 Da, they are classified as macromolecules because of their complex structures and functions in biological systems. However, lipids do not exhibit true polymeric characteristics like proteins and nucleic acids, which are formed from repeating monomer units.
      Conclusion
      - Both Assertion and Reason are true, but the Reason does not correctly explain the Assertion. Lipids are categorized as macromolecules based on their functional roles and structural complexity rather than their molecular weight or polymeric nature.
      Thus, the correct answer is option C: Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.

      Correct answer is option 'A'. Can you explain this answer?

      Prasenjit Khanna answered
      Effect of Low Temperature on Enzymes
      Enzymes are biological catalysts that speed up chemical reactions in living organisms. Temperature plays a crucial role in their activity.
      1. Enzyme Activity at Low Temperatures
      - At low temperatures, enzymes do not function optimally.
      - Enzyme-catalyzed reactions typically slow down because molecular movement decreases.
      2. Kinetic Energy Reduction
      - Enzymes rely on kinetic energy to facilitate interactions with substrates.
      - Lower temperatures result in reduced kinetic energy, leading to fewer effective collisions between enzymes and substrates.
      3. Inactivation of Enzymes
      - Although enzymes are not denatured at low temperatures, their activity can be significantly diminished.
      - The result is a state of inactivation where the enzyme is present but not catalyzing reactions effectively.
      4. Temperature and Reaction Rates
      - The general rule is that for every 10°C decrease in temperature, the reaction rate can drop by about half.
      - This is why many biological processes slow down during colder conditions.
      5. Reversible Nature of Enzyme Inactivation
      - It is important to note that this inactivation is often reversible.
      - When temperatures rise back to optimal levels, enzyme activity can resume.
      Conclusion
      In summary, at low temperatures, enzymes can become inactivated due to reduced kinetic energy and decreased reaction rates. This impact is critical to understanding enzyme functionality, particularly in biological and biochemical contexts.

      Statement i: Nucleic acids are comprised of polynucleotides that contain ribose or deoxyribose sugars.
      - This statement is correct. Nucleic acids, such as RNA and DNA, are polymers (polynucleotides) made up of nucleotides, which include ribose (in RNA) and deoxyribose (in DNA) sugars.
      Statement ii: The building blocks of nucleic acids are amino acids.
      - This statement is incorrect. The building blocks of nucleic acids are nucleotides, not amino acids. Amino acids are the building blocks of proteins.
      Statement iii: The nitrogenous bases adenine, guanine, uracil, cytosine, and thymine are found in nucleic acids.
      - This statement is correct. These nitrogenous bases are integral to nucleic acids. Adenine, guanine, cytosine, and thymine are found in DNA, while adenine, guanine, cytosine, and uracil are found in RNA.
      Statement iv: DNA is a type of nucleic acid that contains ribose sugar.
      - This statement is incorrect. DNA contains deoxyribose sugar, not ribose.
      Conclusion
      Based on the analysis:
      - The correct statements are i and iii.
      - Thus, the correct answer is option C: i, iii, and iv.
      However, the provided answer option "A" is incorrect, as it states that only statements i and iii are correct. The answer should consider the analysis of all statements accurately.

      Relation between torque and angular momentum is similar to the relation between
      • a)
        force and linear momentum
      • b)
        energy and displacement

      Jayant Mishra answered
      Torque is the rate of change of angular momentum.
      Force in linear motion corresponds to Torque in rotary motion.
      Thus, just as Newton’s second law can be written as F=dP/dtF for linear motion, it can be written as T=dL/dt for rotary motion.

      Infinity Academy answered
      Assertion (A): The formation of the enzyme-substrate complex is indeed a transient phenomenon and is crucial for catalysis, as it facilitates the reaction by bringing the substrate into proximity with the active site of the enzyme and lowering the activation energy. This is true.
      Reason (R): The transition state structure is actually the least stable state, not the most stable state, during the conversion of substrate to product. The transition state is an intermediate, high-energy configuration that occurs before the substrate is converted into the product. This makes the Reason false.
      Thus, the Assertion is true, but the Reason is false.

      EduRev NEET answered
      - Statement i is correct because polysaccharides can indeed be classified as homopolymers (like cellulose, which is made only of glucose) or heteropolymers (which contain different types of monosaccharides).
      - Statement ii is incorrect; while cellulose is a homopolymer of glucose, it does not form complex helical structures. Instead, it has a linear structure that forms microfibrils.
      - Statement iii is correct; starch serves as an energy reserve in plants and forms helical structures that can bind iodine, resulting in a blue complex.
      - Statement iv is incorrect; glycogen is a highly branched polysaccharide, not linear, which allows for rapid mobilization of glucose when needed.
      Thus, the correct statements are those in Option B: i and iii.

      - Statement i is correct because all amino acids indeed have an amino group (-NH2) and a carboxyl group (-COOH) attached to the same α-carbon.
      - Statement ii is also correct as there are exactly twenty standard amino acids that are incorporated into proteins.
      - Statement iii is correct because the R group (side chain) varies among amino acids and determines their unique chemical properties.
      - Statement iv is incorrect; while amino acids can be classified as acidic or basic, they can also be neutral and aromatic, making this statement false.
      Thus, the correct statements are i, ii, and iii, leading to the answer being Option A.

      Which of the statements given above is/are correct?
      i. Enzymes require cofactors for catalytic activity, and the protein portion is known as the apoenzyme.
      ii. Prosthetic groups are loosely associated with the apoenzyme and can be easily removed.
      iii. Coenzymes are transiently associated with the apoenzyme and often derived from vitamins.
      iv. Metal ions serve as cofactors and are essential for the activity of certain enzymes.
      • a)
        i and ii
      • b)
        iii and iv
      • c)
        i, iii, and iv
      • d)
        ii and iv
      Correct answer is option 'C'. Can you explain this answer?

      Mohit Rajpoot answered
      - Statement i is correct because enzymes do require cofactors to be catalytically active, and the protein part without the cofactor is indeed called the apoenzyme.
      - Statement ii is incorrect; prosthetic groups are tightly bound to the apoenzyme, not loosely associated.
      - Statement iii is correct because coenzymes are indeed transiently associated with the apoenzyme and are often derived from vitamins, such as NAD from niacin.
      - Statement iv is correct as certain enzymes do require metal ions, which are essential for their catalytic activity, forming coordination bonds at the active site.
      Thus, the correct combination of statements is i, iii, and iv, corresponding to Option C.

      Tertiary structure of protein is formed by __________
      • a)
        Sulphide linkages between different amino acids
      • b)
        Multiple chains of polypeptides held together by hydrogen bonds
      • c)
        Peptide linkages between two amino acids
      • d)
        Hydrogen bond formed by helical or pleated structure
      Correct answer is option 'A'. Can you explain this answer?

      • Primary structure of protein is formed by peptide linkages between two amino acids.
      • Secondary structure, i.e. α-Helix and β-Sheath, of protein is formed by hydrogen bonds.
      • Tertiary structure of protein is formed by sulphide linkages between different amino acids Quaternary structure is formed when multiple chains of polypeptides held together by hydrogen bonds.

      Which type of enzyme catalyzes the transfer of a group (other than hydrogen) between substrates?
      • a)
        Oxidoreductases
      • b)
        Transferases
      • c)
        Hydrolases
      • d)
        Ligases
      Correct answer is option 'B'. Can you explain this answer?
