QUESTION

Rhodopsin is made up of?

OPTIONS

(A) 11 cis retinal
(B) 11 cis retinol
(C) All trans retinal
(D) All trans retinol

ANSWER

(A) 11 cis retinal

EXPLANATION

11-cis-retinal is the correct option because rhodopsin consists of the protein opsin bound to the chromophore 11-cis-retinal. 11-cis-retinol is an alcohol rather than the aldehyde chromophore, while all-trans-retinal and all-trans-retinol are not the light-sensitive chromophore configuration present in resting rhodopsin.
