Put the following events in the order they occur, resulting in depolarization of the olfactory receptor neuron membrane. 1. Adenylyl cyclase converts ATP into cyclic AMP 2. Cl- efflux depolarizes the olfactory receptor neuron 3. Odorant binds to receptor 4. Receptor binds to Golf which dissociates into Galphaolf and beta-gamma subunits 5. cAMP binds and activates cyclic nucleotide-gated Na and Ca2 cation channel 6.
