NEETBotanyBiomolecules (B)
Match List I with List II regarding enzymes and their activity. List I List II A. Low temperature I. Competitive inhibitor B. High temperature II. Enzyme C. Malonate III. Temporarily inactive state D. Succinic dehydrogenase IV. Denatured state Choose the correct answer from the options given below:
Options
- AA - III, B - IV, C - I, D - II
- BA - IV, B - III, C - I, D - II
- CA - III, B - IV, C - II, D - I
- DA - IV, B - III, C - II, D - I
Correct answer
A. A - III, B - IV, C - I, D - II
Step-by-step solution
Low temperature preserves enzymes in a temporarily inactive state, whereas high temperature destroys enzymatic activity because proteins are denatured by heat. Malonate closely resembles the substrate succinate in structure and acts as a competitive inhibitor. Succinic dehydrogenase is the enzyme whose activity is inhibited by malonate. Therefore, the correct matching is A - III, B - IV, C - I, D - II. Answer: A - III, B - IV, C - I, D - II
