FAQs on Biomolecules in One Shot (NCERT) - 1

1. What are biomolecules?
Ans. Biomolecules are organic molecules that are essential for the structure and functioning of living organisms. They include carbohydrates, lipids, proteins, and nucleic acids.
2. What is the significance of biomolecules in living organisms?
Ans. Biomolecules play crucial roles in various biological processes. Carbohydrates provide energy, lipids act as energy reserves and structural components, proteins are involved in cell structure and function, and nucleic acids store and transmit genetic information.
3. How are biomolecules classified?
Ans. Biomolecules are classified into four major types based on their structure and function. Carbohydrates are composed of carbon, hydrogen, and oxygen and are classified as monosaccharides, disaccharides, and polysaccharides. Lipids are hydrophobic molecules and include triglycerides, phospholipids, and steroids. Proteins are made up of amino acids and can be classified as structural, enzymatic, or regulatory. Nucleic acids, such as DNA and RNA, are composed of nucleotides and store genetic information.
4. How are biomolecules important for the human body?
Ans. Biomolecules play critical roles in the human body. Carbohydrates provide energy for cellular processes, lipids form cell membranes and protect organs, proteins are involved in muscle contraction, enzyme catalysis, and immune responses, and nucleic acids store and transmit genetic information.
5. What are some examples of biomolecules?
Ans. Examples of biomolecules include glucose and fructose (carbohydrates), triglycerides and cholesterol (lipids), insulin and hemoglobin (proteins), and DNA and RNA (nucleic acids). These biomolecules are present in various foods and are essential for the proper functioning of the human body.
