Nonsteroid hormones cause ________ in their target cells.
A)cyclic AMP to become ATP
B)cyclic AMP to be decomposed
C)activation of adenylate cyclase
D)inactivation of adenylate cyclase

Question

Quizplus · Accepted Answer

Nonsteroid hormones, such as epinephrine and glucagon, bind to receptors on the plasma membrane of their target cells and activate adenylate cyclase, which in turn converts ATP into cyclic AMP (cAMP). The increased levels of cAMP inside the cell trigger a cascade of intracellular events that lead to the desired physiological response. Therefore, option C is the correct choice as it describes the mechanism by which nonsteroid hormones affect their target cells. Option A and B are incorrect as they either confuse ATP with cAMP or propose a non-existent mechanism. Option D is also incorrect as nonsteroid hormones activate rather than inactivate adenylate cyclase.
