FAQs on DPP for NEET: Daily Practice Problems Biomolecules (Solutions)
| 1. What are the main types of biomolecules that are important for NEET preparation? |  |
Ans. The main types of biomolecules crucial for NEET preparation include carbohydrates, proteins, lipids, and nucleic acids. Each of these biomolecules plays vital roles in biological processes. Carbohydrates serve as energy sources and structural components, proteins are essential for various functions including enzymes and hormones, lipids are important for cell membrane structure and energy storage, and nucleic acids (DNA and RNA) are crucial for genetic information storage and transfer.
| 2. How do enzymes function as biological catalysts in biochemical reactions? | |
Ans. Enzymes act as biological catalysts by lowering the activation energy required for biochemical reactions to occur. They bind to specific substrates at their active sites, forming an enzyme-substrate complex, which stabilizes the transition state and facilitates the conversion of substrates into products. This process increases the reaction rate without being consumed in the reaction, allowing them to be reused multiple times.
| 3. What are the structural differences between DNA and RNA? | |
Ans. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) differ in several structural aspects. DNA is double-stranded, forming a double helix structure with deoxyribose sugar and the nitrogenous bases adenine (A), thymine (T), cytosine (C), and guanine (G). In contrast, RNA is usually single-stranded, contains ribose sugar, and has uracil (U) instead of thymine, pairing with adenine. These structural differences impact their functions in genetic information storage and protein synthesis.
| 4. What role do lipids play in biological systems? | |
Ans. Lipids serve several critical roles in biological systems. They are primary components of cell membranes, providing structural integrity and fluidity. Lipids also function as energy storage molecules, offering a concentrated energy source compared to carbohydrates. Additionally, they are involved in signaling pathways as hormones (such as steroid hormones) and act as insulation in organisms, helping to maintain body temperature.
| 5. Why are proteins considered the workhorses of the cell? | |
Ans. Proteins are often referred to as the workhorses of the cell because they perform a vast array of functions essential for life. They act as enzymes to catalyze biochemical reactions, provide structural support to cells and tissues, transport molecules across membranes, and play key roles in immune responses and cell signaling. Their diverse functions are due to the variety of amino acid sequences and the complex three-dimensional structures they can adopt.
