Question

Quizplus · Accepted Answer

Rhodopsin is a chemical compound found in the rods of the retina that enables us to see in low light conditions. In the dark, rhodopsin is broken down to release a chemical called retinal, which initiates a signal to the brain that allows us to see. As we adjust to brighter conditions, rhodopsin is quickly regenerated, allowing us to adapt to the new lighting conditions. Serotonin, vitrial, and GABA are not directly involved in this process.
