What happens when light strikes the photoreceptor cell of the retina? |
|
Definition
all 11-cis rhodopsin is converted to all-trans rhodopsin
The G protein transducin is activated
phosphodiesterase is activated, and stimulates the breakdown of cGMP
decreased cGMP levels cause Na+ gates to close, leading to the hyperpolarization of the photoreceptor
an inhibitory or stimulatory neurotransmitter is released |
