When Gₒlf is activated, which of the following steps in the olfactory cells contribute to their depolarization?
A) increases in adenylate cyclase only
B) increases in cAMP concentrations only
C) increases in the closure of cAMP gated cation channels only
D) increases in adenylate cyclase activity and cAMP concentrations
E) increases in adenylate cyclase activity, cAMP concentrations and closure of cAMP gated cation channels

Question

Quizplus · Accepted Answer

When Gₒlf is activated in olfactory cells, it leads to an increase in adenylate cyclase activity, which in turn increases cAMP concentrations. These steps contribute to the depolarization of olfactory cells by opening cAMP-gated cation channels, allowing cations to flow into the cell.
