Question

Quizplus · Accepted Answer

During dark adaptation, rhodopsin accumulates in the rods. This allows the rods to become more sensitive to lower levels of light. The rate of rhodopsin breakdown is actually slowed during dark adaptation, and the cones are not activated because they are not as sensitive to low light levels as the rods. The sensitivity of the retina actually increases during dark adaptation.
