Photoreceptor cascade, PDE G*PDE*, G G*, cGMP Cyclic GMP opens cation channels. The fall in [cGMP] in response to light causes these channels to close., Cyclic GMP opens cation channels. The fall in [cGMP] in response to light causes these channels to close. Sodium entry is reduced, hyperpolarising the membrane, Rhodopsin* G*, G*PDE* 5' GMP, Rhodopsin light Rhodopsin*, G* G*PDE*, cGMP G*PDE*, Cyclic GMP opens cation channels. The fall in [cGMP] in response to light causes these channels to close. Calcium entry is reduced. The fall in [Ca2+] triggers light adaptation, reducing the cell's sensitivity
