A major function of cAMP in animal cells is to activate
A) adenylyl cyclase.
B) protein kinase A.
C) protein kinase C.
D) tyrosine kinases.

Question

Quizplus · Accepted Answer

cAMP activates protein kinase A, which then phosphorylates target proteins to bring about cellular responses such as gene expression, ion channel activity, and enzyme regulation. Adenylyl cyclase is the enzyme that synthesizes cAMP, but it is not directly activated by cAMP. Protein kinase C and tyrosine kinases are activated by different cellular signaling molecules.
