Question

Quizplus · Accepted Answer

Rhodopsin is composed of two parts: opsin, a protein found in the membrane of the rod outer segment, and retinal, a derivative of vitamin A that binds to opsin. Together, they form the photopigment that is responsible for converting light into electrical signals in the retina. Cyanolabe and erythrolabe refer to different types of cone cells in the retina, while ganglia are clusters of neurons found throughout the nervous system.
