During dark adaptation ________.
A) the cones are activated
B) rhodopsin accumulates in the rods
C) the sensitivity of the retina decreases
D) the rate of rhodopsin breakdown is accelerated

Question

Quizplus · Accepted Answer

During dark adaptation, rhodopsin accumulates in the rods. This process enables the rods to absorb more light and increase visual sensitivity in low-light conditions. The cones, which are responsible for color vision, are not activated during dark adaptation. The sensitivity of the retina actually increases during dark adaptation, rather than decreasing. The rate of rhodopsin breakdown is actually slowed down during dark adaptation to allow for greater accumulation in the rods.
