Question

Find the correctly matched pair from the following :

• A. Rods - Iodopsin
• B. Cones - Rhodopsin
• C. Iodopsin - Low intensities of light
• D. Rhodopsin - Helps to see in dark

Answer 1

The correct option is D Rhodopsin - Helps to see in dark

Iodopsin is a photosensitive violet pigment in the retinal cones that is similar to rhodopsin but more labile, is formed from vitamin A, and is important in daylight vision.

Rhodopsin is a biological pigment found in the rods of the retina and is a G-protein-coupled receptor (GPCR). It is responsible for the monochromatic vision in the dark; this means it allows the eye to see in black and white in dim light.

So, the correct option is D.
