  1. Chromophore

    Linked via "rod cells"

    Rhodopsin and Vision
    The primary chromophore in vertebrate vision is 11-cis-retinal, an aldehyde derived from Vitamin A. When bound covalently to the opsin protein in the rod cells, this complex is known as rhodopsin. The absorption of a single photon by the chromophore causes an instantaneous isomerization of the 11-cis bond to an all-tra…

  2. Eye

    Linked via "rods"

    The Retina and Photoreception
    The retina is the neural tissue lining the back of the eye. It contains photoreceptor cells—rods and cones—which convert photons into electrical signals.
