rhodopsin

A glowing light bulb at the center radiates outwards with intricate, branching lines resembling neural connections, symbolizing the concept of rhodopsin's role in vision.

Rhodopsin is an extremely light-sensitive receptor protein found heavily concentrated in the rods of the retina. When struck by a single photon, it undergoes a rapid structural change, initiating a complex biochemical cascade that the brain ultimately translates into vision in extremely low-light conditions.
