NEETBotanyBiomolecules (B)
Read the following statements regarding enzyme inhibition: (A) The competitive inhibitor closely resembles the enzyme in its molecular structure. (B) Competitive inhibitors compete with the substrate for the substrate binding site of the enzyme. (C) Inhibition of succinic dehydrogenase by malonate is a classic example of non-competitive inhibition. (D) Such competitive inhibitors are often used in the control of bact
Options
- AOnly three
- BOnly two
- COnly one
- DAll four
Correct answer
B. Only two
Step-by-step solution
Statement (A) is incorrect because a competitive inhibitor closely resembles the substrate in its molecular structure, not the enzyme. Statement (B) is correct as the competitive inhibitor competes with the substrate for the substrate binding site (active site) due to their structural similarity. Statement (C) is incorrect because the inhibition of succinic dehydrogenase by malonate is an example of competitive inhibition, not non-competitive inhibition. Statement (D) is correct as competitive inhibitors are freque
