C)Rods
D)Olfactory receptors

Question

Quizplus · Accepted Answer

Rhodopsin is a type of light-sensitive protein found in the rod cells of the retina, which helps in detecting low light conditions. If rhodopsin is not produced properly, it will affect the functioning of the rod cells, which are responsible for detecting light intensity in dim light, and therefore affect the person's vision in low light conditions. The mutation of rhodopsin would not affect the cones (responsible for detecting color and detail), the lens (which mainly helps to focus the light), or the olfactory receptors (which are responsible for the sense of smell).
