Assertion : Allosteric enzymes show feed back inhibition.
Reason : The inhibition is competitive.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion.
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

C

Explanation

Allosteric Inhibition is noncompetitive inhibition. It is called feedback allosteric inhibition when the end product of a reaction bind to the enzyme allosteric site it
alters the shape of the active site, as a result, it is no longer catalyzed the reaction. For ex : Glucose is changed to glucose 6 phosphate by hex Active and reactive site push the substrate and enzyme molecule toward each other towards enzyme-substrate complex.
