The binding of a regulatory molecule to an allosteric site on a protein that results in the inhibition of the protein is an example of ــــــــــــــــــ.
A)non-competitive inhibition
B)allosteric activation
C)competitive inhibition
D)positive regulation

Question

Quizplus · Accepted Answer

Non-competitive inhibition occurs when a regulatory molecule binds to an allosteric site on a protein and inhibits the protein's activity without competing directly with the substrate's binding site. In contrast, competitive inhibition occurs when a molecule competes with the substrate for the active site of an enzyme. Allosteric activation refers to the binding of a regulatory molecule to an allosteric site on a protein that results in the activation of the protein, while positive regulation generally refers to any process that increases the protein's activity.
