A) Competitive inhibition
B) Non-competitive inhibition
C) Feedback allosteric inhibition
D) Positive feedback
Correct Answer: C
Solution :
Competitive inhibition is the reversible inhibition of enzyme activity due to the presence of substrate analogs. Non-competitive inhibition is the reduction of enzyme activity by a factor that has no real structural similarity with the substrate. Allosteric inhibition is a reversible non-competitive inhibition occurring in case of allosteric enzymes. Herein, the inhibitors are the products or intermediates of reactions catalysed by the enzymes. Hence, it is also known as end product inhibition or feedback inhibition.
