Rods exposed to light will ________.

Question

Quizplus · Accepted Answer

When rods are exposed to light, the pigment rhodopsin breaks down into retinal and opsin, triggering a series of events that ultimately leads to the closure of sodium channels in the photoreceptor cell membrane. This results in hyperpolarization of the cell and a decrease in the release of neurotransmitter, which in turn leads to the signaling of the brain about the presence of light. Therefore, the correct choice is B, hyperpolarise due to the closing of sodium channels.
