cAMP is an example of a
A.second messenger
B.first messenger
C.transcription factor
D.G-protein-coupled receptor
Explanation
Core Concept
cAMP is a small intracellular second messenger produced in response to some extracellular signals. Because many cAMP molecules can be generated after receptor activation, it can relay and amplify a signal to downstream targets. The AP-core concept is second-messenger signaling rather than memorization of one particular downstream kinase.
Correct Answer
Asecond messenger
