(A) Rhodopsin,also known as visual purple,is a biological pigment found in the rod cells of the retina.It is a $G$-protein-coupled receptor that is essential for vision in low-light conditions.Rhodopsin is composed of a protein called opsin and a light-absorbing chromophore called retinal.Retinal is a derivative of Vitamin $A$ (retinol).Therefore,the synthesis of rhodopsin is dependent on the availability of Vitamin $A$.
