FAQs on Biomolecules Practice Questions - DPP for NEET

1. What are biomolecules?
Ans. Biomolecules are molecules that are essential for life and are involved in various biological processes. They include carbohydrates, proteins, lipids, and nucleic acids. These biomolecules play crucial roles in cellular structure, energy storage, enzymatic reactions, and information transfer.
2. How are carbohydrates classified?
Ans. Carbohydrates are classified based on their chemical structure and number of sugar units. Monosaccharides are the simplest carbohydrates and cannot be further hydrolyzed. Disaccharides consist of two monosaccharide units joined by a glycosidic bond. Polysaccharides are complex carbohydrates formed by the polymerization of monosaccharides.
3. What is the function of proteins in the body?
Ans. Proteins have diverse functions in the body. They are involved in structural support, transport of molecules, catalyzing biochemical reactions as enzymes, regulating gene expression, and serving as antibodies in the immune system. Proteins also play a role in muscle contraction, cell signaling, and hormone production.
4. How are lipids important in the body?
Ans. Lipids are essential for various biological processes in the body. They act as a source of energy, provide insulation and protection to organs, and help in the absorption of fat-soluble vitamins. Lipids also play a role in cell membrane structure, hormone synthesis, and serving as signaling molecules.
5. What is the significance of nucleic acids in living organisms?
Ans. Nucleic acids, particularly DNA and RNA, are crucial for the storage and transmission of genetic information in living organisms. DNA carries the genetic instructions necessary for the development, functioning, and reproduction of organisms. RNA is involved in protein synthesis and regulation of gene expression. Nucleic acids are also involved in various cellular processes, such as DNA repair and replication.
