Advanced Biochemistry Q&A
1. What is the primary structure of a protein?
Answer: The linear sequence of amino acids in a polypeptide chain.
2. What is the role of NAD+ in cellular respiration?
Answer: It acts as an electron carrier, accepting electrons during glycolysis and the Krebs cycle.
3. Explain the concept of allosteric regulation.
Answer: Regulation of an enzyme or protein by binding an effector molecule at a site other than
the active site.
4. What is the function of ATP in the cell?
Answer: ATP serves as the main energy currency, powering various biochemical reactions.
5. Describe the Michaelis-Menten equation.
Answer: It relates the rate of enzymatic reactions to substrate concentration, defined by Vmax and
Km.
6. What is the role of ribosomes in protein synthesis?
Answer: Ribosomes facilitate the translation of mRNA into a polypeptide chain.
7. What is oxidative phosphorylation?
Answer: A process that generates ATP through the electron transport chain and chemiosmosis.
8. Define the term enzyme inhibition.
Answer: A process where the activity of an enzyme is decreased or halted by a molecule.
9. Differentiate between competitive and noncompetitive inhibition.
Answer: Competitive inhibitors bind to the active site, while noncompetitive inhibitors bind
elsewhere.
10. What is a coenzyme?
Answer: An organic non-protein compound that assists enzyme function.
