Which one of the following statements is not correct?
Which one of the following statements is not correct?
Options
- ARetinal is the light absorbing portion of visual photo pigments.
- BIn retina the rods have the photopigments rhodopsin while cones have three different photopigments.
- CRetinal is a derivative of Vitamin C.
- DRhodopsin is the purplish red protein present in rods only.
Correct answer
C. Retinal is a derivative of Vitamin C.
Step-by-step solution
Carotene is the source of retinal which is involved in the formation of rhodopsin of rod cells. Retinal, a derivative of vitamin A, is the light-absorbing part of all visual photopigments. Rods have rhodopsin pigment while cones have three different photopigments, iodopsin, porpyrosin, and cyanopsin. Rhodopsin is a purplish red protein, also known as visual purple, and is associated with vision under low light.
