Question

Color perception in humans is due to ________.
A. Rhodopsin pigment in rod cells
B. Rhodopsin pigment in cone cells
C. Iodopsin pigment in rod cells
D. Iodopsin pigment in cone cells.

Answer 1

Hint: Rod cells, or rods, are photoreceptor cells. These cells are found in the retina of the eye. They have the capability that can work in less serious light than the other sort of visual photoreceptor, cone cells. Rods are amassed at the external edges of the retina and are utilized in fringe vision

Complete answer:
There are two sorts of photoreceptor cells in the retina:
-Rods: The photoreceptor cells that contain rhodopsin color and are connected with the scotopic vision of the eye for example vision under low light.
-Cones: The photoreceptor cells that contain iodopsin, porphyrin, and cyanopsia colors. These cells are related to the sunlight vision and shading vision of the eyes.
Henceforth, colour perception in people is because of iodopsin in cone cells. Along these lines, the right answer is 'Iodopsin shade in cone cells'.
Hence, option (A) is correct.

Note: Photoreceptor proteins found in the cone cells of the retina that is the premise of shading vision. Iodopsin, the cone shade framework in the chicken retina, is a nearby simple of the visual purple rhodopsin that is utilized in night vision. Iodopsin comprises the protein segment and abounds chromophore, retinal. When presented to light, the color promptly photobleaches separating into opsin and retinal. Similar to rod cells, cone cells contain rhodopsin-like shade called iodopsin or photopsin. Much the same as rhodopsin, photopsin contains opsin, and retinal aside from the opsin segment shift marginally by a couple of amino acids.
