WebThe cells in the retina that produce the visual experience are rods and cones. Rods are active in dim light and cones in daylight. Mutations in rods that cause them to die trigger most inherited retinal degeneration. Cones can remain alive after nearly all the rods die, but they retract key parts of the cells and appear “dormant.” WebAns. Both rods and cones contain light sensitive pigments known as rhodopsins. Each rhodopsin molecule consists of a large protein, opsin, which behaves as an enzyme, and a small carotenoid molecule, retinal, a derivative of vitamin A. When a quantum of light strikes the photo pigment and is absorbed by the rhodopsin molecule, retinal is ...
