During the dark cycle, Na+ gated channels are open and retinal is in the 11-cis form. When a light photon hits a photoreceptor this all changes. Describe opsin activation using the terms PDE, cGMP, Na+ channels, transducin, neurotransmitters, and 11-trans retinal. +3 points if you a) define bleaching, b) define regeneration, and c) explain why form is important to function in this process. [+1 point if answer correctly any of these 3 parts).
