Question

The opening of Na+/Ca2+ channels by cAMP produces a graded depolarization in the olfactory bulb.

A. True
B. False

Answer 1

The opening of Na+/Ca2+ channels by cAMP does not produce a graded depolarization in the olfactory bulb.

Step-by-step explanation:

The opening of Na+/Ca2+ channels by cAMP does not produce a graded depolarization in the olfactory bulb.

Na+/Ca2+ channels are not directly activated by cAMP. Instead, cAMP acts as a second messenger in a signaling pathway, which eventually leads to the opening of Ca2+ channels and the release of neurotransmitters in the olfactory bulb. This release of neurotransmitters can then produce a graded depolarization in the olfactory bulb.

So, the statement is FALSE.
