Answer
The conversion of 11-cis retinal to all-trans retinal is called isomerization.
Work Step by Step
Rods and cone contain light-sensitive pigments.. The pigment in rods is rhodopsin also known as visual purple. It is composed of a protein called opsin and a Vitamin A derivative called retinal. All rods contain the same type of rhodopsin which makes them most sensitive to light of wave length 500 nm. Cones have a pigment call iodopsin. The retinalin this pigment is the same moiety as that in rods. In contrast to rods however, cones have three different opsin moieties; therefore, cones can detect light of three different wave lengths which are interpreted as red, blue, and green colors.
