6. Retinal is a conjugated chromophore that is responsible for our ability to see. Retinal iscovalently bound to the protein Rhodopsin through a lysine residue.CHORhodopsin |NH2+6.1 Draw a non-enzymatic mechanism to describe the formation of the imine betweenretinal and lysine. For simplicity, use R-NH2 to represent lysine.6.2 During the visual cycle, retinal absorbs a photon and this leads to a conformation change.The bond between retinal and the protein is hydrolyzed and retinal is disconnected fromthe protein. Draw an arrow-pushing mechanism describing this hydrolysis step(remember that this is the reverse reaction for imine formation).

Approach to solving the question: biochemistry Detailed explanation:

Answered: 6. Retinal is a conjugated chromophore…
