Question

Quizplus · Accepted Answer

Rhodopsin consists of an opsin protein and a retinal chromophore, which together form the photopigment molecule. The other options are incorrect: A is incorrect because rhodopsin is the photopigment in the rod cells, not the red cones; C is incorrect because rhodopsin is actually most highly concentrated outside of the fovea, in the peripheral retina; D is incorrect because rhodopsin is rapidly broken down in the presence of light, not the absence of light; and E is incorrect because rhodopsin does not contain a derivative of vitamin B12.
