Rhodopsin is a light-sensitive receptor protein located in the rod cells of the retina, crucial for low-light (scotopic) vision. It changes shape when exposed to light, initiating a biochemical cascade that results in a nerve impulse sent to the brain.
congrats on reading the definition of rhodopsin. now let's actually learn it.
The thin layer of tissue at the back of the eye that contains cells sensitive to light, where phototransduction (conversion of light into electrical signals) occurs.
Rod Cells: A type of photoreceptor cell in the retina that is highly sensitive to light and enables vision in low-light conditions.
Phototransduction: The process by which photoreceptor cells convert light into electrical signals, which are then processed by the brain as visual information
