Select from the dropdown lists to complete the text.

Rhodopsin contains ( 11-cis-retinal, all-trans-retinal, all-trans-retinol ). When light hits this substance it becomes ( all-trans-retinal, 11-cis-retinal, all-trans-retinol ), which is then broken up into 11-cis-retinal + ( Vitamin A, Vitamin D, Vitamin C )
