| rhodopsin |
ro-DOP-sin A pigment molecule stored in rod cells of the retina. Light splits rhodopsin, which depolarizes the rod cell and provokes an action potential. 644

| rhodopsin |
The light-sensitive receptor protein in rod cells of the retina. When rhodopsin absorbs a photon of light, its molecular shape is changed and it releases energy, leading ultimately to an electrical signal.

| rhodopsin kinase |
an enzyme that phosphorylates activated rhodopsin, enabling it to bind arrestin and thus inhibiting its binding to transducin; the reaction occurs in the deactivation of activated rhodopsin during the visual cycle.

| rhodopsin |
Rhodopsin is formed when a protein called opsin is chemically linked to a specialized form of Vitamin A. Rhodopsin resides almost exclusively in the outer segments of rod photoreceptor cells and can only be formed in the dark. When light strikes, the rhodopsin molecule changes shape, generating the initial signal in the visual process. Ultimately, the vitamin A splits off from the opsin protein but can be reattached in the dark. ...
