E)calmodulin.

Question

Quizplus · Accepted Answer

cAMP affects cell activities by directly interacting with protein kinase A (PKA) regulatory subunits. This interaction causes the regulatory subunits to release the catalytic subunits of PKA, thereby activating the enzyme to phosphorylate various target proteins in the cell.
