FAQs on Biomolecules Video Lecture - Crash Course for NEET

1. What are the major types of biomolecules relevant for NEET preparation?
Ans. The major types of biomolecules relevant for NEET preparation include carbohydrates, proteins, lipids, and nucleic acids. Each of these biomolecules plays a vital role in biological processes and is essential for the structure and function of living organisms.
2. How do enzymes function as biological catalysts in biomolecule reactions?
Ans. Enzymes function as biological catalysts by lowering the activation energy required for biochemical reactions to occur. They bind to substrates to form an enzyme-substrate complex, facilitating the conversion of substrates into products while remaining unchanged themselves.
3. What is the significance of nucleic acids in living organisms?
Ans. Nucleic acids, primarily DNA and RNA, are crucial for storing and transmitting genetic information. DNA carries the genetic blueprint of an organism, while RNA plays a key role in protein synthesis and gene expression, making them essential for life processes.
4. How do lipids differ from other biomolecules in terms of structure and function?
Ans. Lipids differ from other biomolecules in that they are hydrophobic or amphiphilic molecules, meaning they do not dissolve well in water. They serve various functions, including energy storage, forming cell membranes, and acting as signaling molecules, which distinguishes them from hydrophilic biomolecules like carbohydrates and proteins.
5. What role do carbohydrates play in cellular processes?
Ans. Carbohydrates play a vital role in cellular processes by serving as a primary source of energy for cells. They also contribute to structural components in cell walls of plants (cellulose) and are involved in cell recognition processes through glycoproteins and glycolipids on cell surfaces.
