Question

Quizplus · Accepted Answer

Rhodopsin is the photopigment found in the rod cells of the retina and it consists of opsin (a protein) and retinene (a derivative of vitamin A). Option A is incorrect because rhodopsin is not found in red cones but rather in rod cells. Option C is also incorrect because the fovea contains mostly cone cells and therefore has low levels of rhodopsin. Option D is incorrect because rhodopsin is rapidly broken down in the presence of light, not in its absence.
