A molecule or other agent that alters enzyme function by changing the enzyme's shape is called a(n):
A) cofactor.
B) coenzyme.
C) allosteric effector.
D) proenzyme.

Question

Quizplus · Accepted Answer

Allosteric effectors are molecules that bind to a site on an enzyme that is different from the active site, but still results in a change in the enzyme's shape and function. This can either activate or inhibit the enzyme's activity. Cofactors and coenzymes are molecules that assist enzyme function, but do not necessarily alter the enzyme's shape. Proenzymes are inactive enzyme precursors that require activation.
