Please help me answer this question. Thanks a lots.
Some Archaea have ATPases with different H+:ATP ratios. Assumes the delta Gp for ATP synthesis in one such organism is -518 mV. The minumum delta P required to generate ATP with a typical bacterial ATPase is about -173 mV. ATPases also function in reverse. Which ATPase, archael or bacterial, when functioning in reverse, produces a greater delta P per ATP hydrolyzed?
