During the odorant response in the cilia of olfactory neurons, the second messenger _______, leads to the opening of ion channels in the plasma membrane of olfactory neurons and the production of a nerve impulse. A) Ca²⁺ B) cAMP C) cGMP D) IP₃

Question

Quizplus · Accepted Answer

The second messenger involved in the odorant response in olfactory neurons is cAMP (cyclic adenosine monophosphate). It activates protein kinase A, which then opens ion channels in the plasma membrane of the olfactory neurons, leading to the production of a nerve impulse.
