In the case of non-competitive inhibition, the inhibitor may bind to which of the following?
A) only free enzyme
B) only enzyme-substrate complex
C) both free enzyme and enzyme?substrate complex
D) only to substrate
E) only to the substrate binding site of the enzyme

Question

Quizplus · Accepted Answer

In non-competitive inhibition, the inhibitor can bind to both the free enzyme and the enzyme-substrate complex, causing a decrease in enzyme activity. This type of inhibition does not compete with the substrate for binding at the active site of the enzyme, but instead binds to a different site on the enzyme, altering its shape and reducing its activity. Therefore, choices A, B, D, and E are incorrect.
