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.
