In signal transduction what is an effector enzyme?
A)An integral membrane protein that changes conformation upon binding of a ligand to a cell surface receptor.
B)A small molecule that diffuses within a cell and carries a signal to its ultimate destination.
C)A protein bound on the interior of a cell membrane that generates a second messenger.
D)Protein bound on the exterior surface of a cell and is the receptor site for a ligand.

Question

Quizplus · Accepted Answer

An effector enzyme is a protein that is bound on the interior surface of a cell membrane and is responsible for generating a second messenger in signal transduction pathways. This second messenger is often a small molecule like cAMP or IP3 that helps transmit the signal to the ultimate effector proteins.
