What is rhodopsin and what is its function? - Studybuff

SpletRhodopsin is a pigment of the retina, the light-sensitive inner lining of the back of the eye. The pigment is responsible for both the formation of the photoreceptor cells – specialized neurons that absorb light and convert that energy into a nerve signal – and the first events in the perception of light. SpletWhen rhodopsin absorbs light, retinal changes from 11-cis to all-trans retinal. The retinal-scotopsin complex breaks down allowing them to separate. This b reakdown is known as the bleaching of the pigment. The breakdown of rhodopsin triggers a transduction process involving a rapid cascade of intermediates. SpletThe light sensitivity of the photoreceptors results from the presence of visual pigment molecules contained within their outer segments. One rod pigment called rhodopsin, and three cone pigments are in the human retina; non-mammalian species may have four or more cone visual pigments. In humans, there is one type of rod cell and three cone ... create folder ftp command line
