Malonate inhibits the growth of pathogenic bacteria by inhibiting the activity of

Topic: NEET PYQ

Answer: B. Full step-by-step solution below.

  1. ADinitrogenase
  2. Bsuccinic dehydrogenase
  3. CAmylase
  4. DLipase

Correct answer: B

Solution

(b) The competitive inhibitor competes with the substrate for the substrate binding site of the enzyme. Consequently, the substrate cannot bind and as a result, the enzyme action declines, e.g. inhibition of succinic dehydrogenase by malonate which closely resembles the substrate succinate in structure. Such competitive inhibitors are often used in the control of bacterial pathogens.
