FAQs on Biomolecules -Biology, Class 11 Video Lecture

1. What are biomolecules?
Ans. Biomolecules are molecules that are essential for life and play a crucial role in various biological processes. They include carbohydrates, lipids, proteins, nucleic acids, and other organic compounds found in living organisms.
2. What is the importance of biomolecules in biology?
Ans. Biomolecules are essential for the structure, function, and regulation of cells and organisms. They provide energy, act as building blocks for cells, carry out metabolic processes, store and transmit genetic information, and participate in various biochemical reactions.
3. How are biomolecules classified?
Ans. Biomolecules are classified into four major categories: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates provide energy and structural support, lipids store energy and form cell membranes, proteins perform various functions in cells, and nucleic acids store and transmit genetic information.
4. What are the functions of proteins in biomolecules?
Ans. Proteins have diverse functions in living organisms. They act as enzymes, which catalyze biochemical reactions, transport molecules across cell membranes, provide structural support, regulate gene expression, participate in immune responses, and serve as signaling molecules.
5. How do nucleic acids contribute to biomolecules?
Ans. Nucleic acids, such as DNA and RNA, store and transmit genetic information in cells. DNA carries the genetic instructions for the development and functioning of living organisms, while RNA plays a crucial role in protein synthesis by transferring the genetic code from DNA to ribosomes.
