During sustained illumination, a decrease in intracellular _______ prevents all nucleotide gated channels in photoreceptors from closing.

Question

Quizplus · Accepted Answer

During sustained illumination, there is a decrease in intracellular calcium levels in photoreceptors. This decrease in calcium prevents cyclic nucleotide-gated channels from closing, which is crucial for the phototransduction process.

During Sustained Illumination, a Decrease in Intracellular _______ Prevents All
