Put the following in the correct order for the activity of a photoreceptor in the "light" (2 points) • 1. cis-retinal absorbs light and shifts to trans-retinal form • 2.decrease in cGMP levels closes gated Na+ channels • 3. cGMP phosphodiesterase activity results in the breakdown of cGMP • 4. bleaching of opsin • 5. bipolar cells are no longer inhibited • 6. photoreceptor becomes hyperpolarized & glutamate release stops • 7. opsin activates transducin (a G protein) in the cell membrane of the disc • 8. transducin activates an effector protein called cGMP Phosphodiesterase • 9. ganglion cells generate AP • 10. processing of signals in primary visual cortex
