Question

The photopigment in rods is called
A)chlorophyll
B)rhodopsin
C)opsin
D)melanin
E)retinal

Accepted Answer

The photopigment in rods is known as rhodopsin, which consists of a protein called opsin and a chromophore called retinal. Chlorophyll is a photopigment found in plants, not in the human eye. Opsin is a component of rhodopsin, but it alone is not the photopigment. Melanin is a pigment that gives color to skin, hair, and eyes, but it is not a photopigment involved in vision. Retinal is a component of rhodopsin, but it alone is not the photopigment.
