Question

Identify which of the following depicts the correct sequence of events in G protein-coupled receptor signaling.

Accepted Answer

Ligand binds to G protein-coupled receptor → Activation of G protein → Activation of adenylyl cyclase → cAMP synthesis from ATP → Activation of protein kinase A → Phosphorylation of target proteins.

Answer

Ligand binds to G protein-coupled receptor → Activation of adenylyl cyclase → Activation of G protein → cAMP synthesis from ATP → Activation of protein kinase A → Phosphorylation of target proteins.
