Inhibition of succinic dehydrogenase enzyme by malonate is a classical example of:

  1. A
    Feedback inhibition
  2. B
    Competitive inhibition
  3. C
    Non-competitive inhibition
  4. D
    Enzyme activation

Solution & Step-by-step Explanation

Malonate closely resembles the substrate succinate in structure. It competes with succinate for the binding site of succinic dehydrogenase, thereby inhibiting its activity. This is competitive inhibition.
