A common light-sensitive pigment that absorbs light and changes shape thereby altering the charge across the membrane of a photoreceptor is:

Question

Quizplus · Accepted Answer

Rhodopsin is a common light-sensitive pigment found in the retina of the eye, and it undergoes a structural change when exposed to light, triggering a nerve impulse that is sent to the brain. This process of "phototransduction" is essential for vision in low light conditions. Carotene, chlorophyll, glutamate, and tyrosine are not light-sensitive pigments that are involved in phototransduction in the eye.
