Some photosynthetic bacteria contain the protein bacteriorhodopsin, which absorbs light and pumps protons out of the cell directly. Briefly describe how such a cell could use bacteriorhodopsin and an H+ATPase to make ATP using light.

Some photosynthetic bacteria contain the protein bacteriorhodopsin, which absorbs light and pumps protons out of the cell directly , this event help in maintaining the proton gradient into the cells from which F⁰-F¹ complex utilitise those protons and make ATP . On exposure to light, bacteriorhodopsin would pump protons out of the cell, establishing a proton gradient. This proton gradient could be used by an H+ATPase to generate ATP.
