Describe the events leading up to the depolarization and generation of an action potential by an olfactory receptor cell
What will be an ideal response?
The depolarization of an olfactory receptor cell begins with the binding of airborne odorant molecules to their receptors on the membranes of olfactory dendrites. Binding results in the activation of the enzyme adenylate cyclase and formation of cyclic AMP (cAMP). The cAMP opens sodium ion channels in the plasma membrane, leading to depolarization of the olfactory receptor cell's axon.
