The bleaching of rhodopsin by light
A) triggers inhibitory effects.
B) closes rod sodium channels.
C) hyperpolarizes the rods.
D) reduces the release of glutamate from rods.
E) all of the above

Question

Quizplus · Accepted Answer

The bleaching of rhodopsin by light triggers a series of events that lead to the closure of rod sodium channels, hyperpolarization of the rod cell membrane, and reduction in the release of glutamate from rods, which ultimately results in inhibitory effects on the bipolar and ganglion cells in the retina. Therefore, all of the above choices are correct.
