Cryptochrome and rhodopsin pigments. Rhodopsin is a pigment found in the rod photoreceptor cells in the retina of the human eye,where it absorbs light falling on the retina. Here,four rhodopsin molecules are shown embedded in the membrane (across top and bottom) of cells in the eye's retina. The membrane is shown as a lipid bilayer. Inside the cell is a molecule of a cryptochrome (centre),anchored to the membrane (pink strands). Cryptochromes are capable of mediating a response to light falling on the retina,triggering a cascade of other reactions (the CRY pathway). They are also involved in the circadian rhythm | |
