Cellular responses to hormones that initiate second-messenger systems include ________.
A) possible activation of several different second-messenger systems
B) cyclic AMP phosphodiesterase formation of an active second messenger
C) formation of a specific protein kinase that acts on a series of extracellular intermediates
D) hormone binding to intracellular receptors

Question

Quizplus · Accepted Answer

When hormones initiate second-messenger systems, they can activate multiple different second-messenger systems, such as cyclic AMP, inositol triphosphate, and calcium signaling pathways. The specific second-messenger system activated depends on the type of hormone and the target cell.
