A Receptor Potential May Cause All of the Following Responses

Question

A receptor potential may cause all of the following responses except
A) increase neurotransmitter release.
B) decrease neurotransmitter release.
C) cause hyperpolarization.
D) cause depolarization.
E) turning off the original stimulus.

Accepted Answer

A receptor potential is a change in the membrane potential of a sensory receptor that occurs in response to a stimulus. This change in membrane potential can result in the release of neurotransmitters, either increasing or decreasing their release depending on the nature of the stimulus. Additionally, receptor potentials can cause hyperpolarization (making it more difficult to generate an action potential) or depolarization (making it more likely to generate an action potential). However, a receptor potential is not capable of turning off the original stimulus – that is a function of feedback mechanisms or adaptation.
