In the Mechanism of Vertebrate Olfaction, a G Protein Activates

Question

In the mechanism of vertebrate olfaction, a G protein activates the enzyme
A) cGMP phosphodiesterase.
B) phospholipase C.
C) adenylyl cyclase.
D) transducin.

Accepted Answer

In vertebrate olfaction, the G protein Golf activates adenylyl cyclase, which increases the levels of cAMP, leading to the opening of ion channels and the generation of a nerve impulse.
