Bacteriorhodopsin is a retinal based proton pump, which can contribute to the generation of

Answer: ATP

Bacteriorhodopsin is a proton pump found in bacteria. Bacteriorhodopsin is a seven helical transmembrane protein that contains one molecule of retinal. when light is detected by retinal molecule, it changes the confirmation of the Bacteriorhodopsin and makes it to act as a proton pump. Then Bacteriorhodopsin moves protons from the cytoplasm to the extracellular space, resulting in proton gradient which is subsequently used for generation of ATP.
