Reduced concentrations of the molecule cGMP causes channels in the cell membrane of photoreceptors to _______, which _______ the cell.

Question

Quizplus · Accepted Answer

Reduced concentrations of cGMP cause the channels in the cell membrane of photoreceptors to close, which leads to the hyperpolarization of the cell. This is a key process in the phototransduction pathway, where the decrease in cGMP is a response to light, leading to the closure of cGMP-gated ion channels, reducing the influx of positive ions and thus hyperpolarizing the cell.
