  1. Question 1

    Q1. Malonic acid resembles succinic acid and competes for the active site of succinate dehydrogenase. This type of interaction is called:

    • A) Non-competitive inhibition
    • B) Competitive inhibition
    • C) Irreversible inhibition
    • D) Uncompetitive inhibition

    Answer: Competitive inhibition

    Explanation: Competitive inhibitors like malonate mimic the substrate's shape; non-competitive inhibitors bind elsewhere, failing to resemble the substrate's molecular structure.
