Question
What is called the changing in the retinal shape when eyes exposed to the light?A) isomerizationB) visual pigment bleachingC) Pigment epitheliumD) Opponent process
Solution
The change in the retinal shape when eyes are exposed to light is called A) Isomerization. This process involves the conversion of the 11-cis retinal compound of the visual pigment into all-trans retinal when it absorbs light. This change in shape triggers a series of events that leads to an electrical response in the photoreceptor cells.
