Place the following steps in the correct order for transduction of a chemical odorant into a nerve signal. 1.Odorants reach receptors in the cilia of olfactory neurons. 2.cAMP opens ions channels that allow sodium and calcium ions to enter the cell. 3.The G-protein activates an enzyme, adenylate cyclase, to convert ATP into cyclic AMP (cAMP). 4.The binding of an odorant activates a G-protein which then detaches from the receptor. 5.The membrane is depolarized. Depolarization that reaches threshold at the axon hillock triggers an action potential and transduction has been achieved.
