Consider this pathway: epinephrine $\rightarrow$ G protein-coupled receptor $\rightarrow G$ protein $\rightarrow$ adenylyl cyclase $\rightarrow$ cAMP. Identify the second messenger. $$ \begin{array}{ll}{\text { (A) } \operatorname{cAMP}} & {\text { (C) GTP }} \\ {\text { (B) Grotein }} & {\text { (D) adenylyl cyclase }}\end{array} $$
Consider this pathway: epinephrine → G protein-coupled receptor → G protein → adenylyl cyclase → cAMP. The second messenger in this pathway is cAMP G protein-coupled receptor G protein adenylyl cyclase
Consider this pathway: epinephrine → G protein-coupled receptor → G protein → adenylyl cyclase → cAMP → many cellular responses The ligand in this pathway is ________. a. cAMP b. epinephrine c. G protein d. Adenylyl cyclase e. G protein-coupled receptor
