Which of the following statements accurately describes the changes in the membrane potential of a photoreceptor cell when light rays strike its photopigments?

Question

Quizplus · Accepted Answer

When light rays strike the photopigments of a photoreceptor cell, it undergoes hyperpolarization. This means that the cell becomes more negative, and it becomes less likely to fire an action potential. This is due to the closure of ion channels in the plasma membrane of the cell, which reduces the influx of positively charged ions (such as sodium) and increases the efflux of negatively charged ions (such as potassium). This change in membrane potential is then transmitted to other cells in the retina, ultimately leading to visual perception.
