What are the parts of riodescolour?

Rhodopsin, a visual pigment found in the photoreceptor cells of the retina, consists of two main parts: opsin and retinal. Opsin is a protein that forms the structure of the pigment, while retinal is a light-sensitive molecule derived from vitamin A. When light hits rhodopsin, retinal undergoes a conformational change, triggering a biochemical cascade that ultimately leads to visual perception. This process is crucial for low-light vision and is fundamental to the function of rod cells in the retina.
