Opsin refers strictly to the apoprotein (without bound retinal). When an opsin binds retinal to form a holoprotein, it is referred to as Retinylidene protein. However, the distinction is often ignored, and opsin may refer loosely to both (regardless of whether retinal is bound). Opsins are G-protein-coupled receptors (GPCRs) and must bind retinal ⁠— typically 11-cis-retinal ⁠— in order to be photosensitive, since the retinal acts as the chromophore.

WebBoth rods and cones contain light sensitive pigments known as rhodopsins.
