Rhodopsin is an organic compound called a Visual Pigment. The absorption of lights by visual pigments is the crucial first step in the process of photoreception.In the presence of light, the protein opsin is activated allowing retinal to bind to its active site (retinal synthesized with vitamin A).hodopsin is a G protein coupled receptor (GPCR) responsible for activating a G protein called transducin.
