The 12 pages that link to Rhodopsin, each with the reason it gives.

• G protein-coupled receptorBroader topic: It is a specialized GPCR whose ligand is formed when light changes retinal.

• Cone cellCompared with: Unlike cone photopsins, rhodopsin supports the rod system’s high sensitivity in low light.

• Vitamin ARelated: Vitamin A supplies the retinal chromophore that rhodopsin needs to detect dim light.

• Photoreceptor cellBroader topic: In rod cells, this pigment initiates the cascade after absorbing a photon.

• PhototransductionRelated: Its light-triggered shape change initiates the rod phototransduction cascade.

• RetinalRelated: Retinal’s best-known vertebrate complex starts the rod response to dim light.

• Rod cellRelated: A photon changes its retinal molecule, initiating the rod’s response to light.

• OpsinBroader topic: It is the best-studied vertebrate opsin complex and mediates dim-light vision.

• Vitamin A deficiencyRelated: Vitamin A shortage limits the retinal needed to rebuild this pigment after light exposure.

• Night visionBroader topic: Its activation lets rods respond to individual photons.

• ChlamydomonasRelated: Channelrhodopsins in Chlamydomonas directly convert light into electrical signals.

• Human visionBroader topic: The actual molecule that absorbs incoming photons and starts the signal.
