Bacteriorhodopsin is a proton pump found in Archaea, it takes light energy (photons of light) and coverts it into chemical energy, ATP, by creating electrochemical proton gradient that drives the synthesis of ATP by an ATP synthase, then ATP can be used by the cell for cellular functions. Bacteriorhodopsin forms chains in a cylindrical shape(each subunit consist of seven alpha-helical membrane spanning segments ), which contain retinal molecule which is a light- absorbing pigment(chromophore) that is related to vitamin A .
