Determine the correctness or otherwise of the following Assertion (a) and the Reason (r): Assertion: A very low amount of inhibitor can act as an activator for allosteric enzymes. Reason: Allosteric enzymes follow Michaelis-Menten kinetics. Options: (A) both (a) and (r) are true and (r) is the correct reason for (a) (B) both (a) and (r) are true but (r) is not the correct reason for (a) (C) (a) is true but (r) is false (D) (a) is false but (r) is true
Determine the correctness or otherwise of the following Assertion (a) and the Reason (r):
Assertion: A very low amount of inhibitor can act as an activator for allosteric enzymes.
Reason: Allosteric enzymes follow Michaelis-Menten kinetics.
Options:
(A) both (a) and (r) are true and (r) is the correct reason for (a)
(B) both (a) and (r) are true but (r) is not the correct reason for (a)
(C) (a) is true but (r) is false
(D) (a) is false but (r) is true
Answer
Answer: (C) (a) is true but (r) is false
Explanation: A very low amount of inhibitor can indeed act as an activator for allosteric enzymes, but allosteric enzymes do not follow Michaelis-Menten kinetics; they exhibit cooperative binding. Therefore, (a) is true but (r) is false.
