Place the Following Steps in the Correct Order for Transduction

question 35

Multiple Choice

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.
