Quizplus · Accepted Answer

When a photon is captured by a retinal photopigment, it changes the shape of the molecule, leading to a series of chemical reactions that ultimately result in a nerve impulse being sent to the brain. This change in shape is essential for the photopigment to function and is the basis of visual perception.
