Quizplus · Accepted Answer

Rhodopsin is the pigment found in rods that breaks down when light strikes it. This process initiates the signal transduction pathway that ultimately leads to the perception of light in the retina. Scotopsin is a protein found in conjunction with rhodopsin, but it does not break down upon light exposure. Melanin is a pigment found in skin and hair, but not in the retina. Vitamin A is necessary for the synthesis of rhodopsin, but it is not the chemical that breaks down upon light exposure.
