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

Question

Quizplus · Accepted Answer

Cellular responses to hormones that initiate second-messenger systems can result in the activation of several different second-messenger systems, such as cyclic AMP, inositol triphosphate (IP3), and diacylglycerol (DAG). Different types of cells and different hormones can activate different second-messenger systems, leading to diverse physiological responses. The other answer choices are not accurate descriptions of second-messenger systems.
