One of the reasons that rods are more sensitive to dim light than cones is that
A) they form graded potentials instead of the action potentials formed by cones.
B) they are found in the eye in greater numbers than cones.
C) it takes less light to break apart rhodopsin than the photopigments found in cones.
D) rhodopsin shows a peak response to all wavelengths in the visual spectrum.

Question

Quizplus · Accepted Answer

Rods contain a photopigment called rhodopsin that is more easily broken apart by light than the photopigments found in cones. This leads to a greater sensitivity to dim light in rods compared to cones.
