Question

Rhodopsin is found in?

1) rods
2) cones
3) visual pigments
4) sodium pumps
5) neurotransmitters

Answer 1

Rhodopsin is a visual pigment found in the rod cells of the retina, essential for low-light vision.

Step-by-step explanation:

Rhodopsin is a visual pigment that is specifically found in rod cells of the retina. Rod cells are responsible for vision under low-light conditions. Rhodopsin is composed of a protein called opsin and a molecule called retinal; when light hits this complex, it causes a structural change in retinal that activates rhodopsin and starts a cascade of events leading to the closing of sodium channels in the photoreceptor cell.
