Question

multiple choice question
for all receptors, stimulation of a receptor results in a change in

the membrane potential
the state of the receptor from active to inactive
gene expression
the shape of the receptor

Explanation:

When a receptor is stimulated, it leads to a change in the membrane potential. This is a fundamental response in receptor - mediated processes. Receptor activation typically does not directly cause a change from active to inactive state (it activates an inactive receptor), gene expression changes are usually downstream and not an immediate result, and while receptor shape can change, the most immediate and universal change is in membrane potential.

Answer:

A. the membrane potential
