Both mitochondria and chloroplasts use electron transport to pump protons, creating an electrochemical proton gradient, which drives ATP synthesis. Are protons pumped across the same (analogous) membranes in the two oraganelles? Directionality of the pump? Is ATP synthesized in analogous compartments? Fully explain your answers.
