Quizplus · Accepted Answer

Visual pigments are made from opsin, which is a protein, and retinal, which is a type of vitamin A derivative. When retinal absorbs light, it changes shape and causes a conformational change in the opsin protein, leading to the activation of the visual pigment and the initiation of the visual transduction cascade. None of the other options listed are involved in the process of visual pigments.
