The membrane potential of rod and cone cells is around
A)-70 mV in the dark,and the cells depolarize in the light.
B)-70 mV in the dark,and the cells hyperpolarize in the light.
C)-35 mV in the dark,and the cells hyperpolarize in the light.
D)-35 mV in the dark,and the cells depolarize in the light.

Question

Quizplus · Accepted Answer

In the dark, rod and cone cells have a membrane potential of about -35 mV. When exposed to light, these cells hyperpolarize, meaning their membrane potential becomes more negative.
