Which molecule is a first messenger but not a second messenger?
A) G protein
B) Cyclic AMP
C) Acetylcholine
D) Protein kinase
E) Adenylyl cyclase
First Messenger
A signaling molecule that binds to a receptor at the surface of a cell, initiating a series of intracellular events that lead to a biological response.
Acetylcholine
A neurotransmitter in both the peripheral and central nervous system that is involved in muscle activation, heart rate, and memory function.
Cyclic AMP
Cyclic AMP (cAMP) is a second messenger important in many biological processes, serving as a signaling molecule that transduces extracellular signals into cellular responses.
