Quick Summary

The F1F0-proton-translocating ATPase, also known as ATP synthase, is a crucial enzyme found in the inner mitochondrial membrane and chloroplasts. It plays a vital role in cellular energy production by synthesizing adenosine triphosphate (ATP), the primary energy currency of cells.12

ATP synthase harnesses the energy from a proton gradient—created by electron transport chains during cellular respiration or photosynthesis—to convert adenosine diphosphate (ADP) and inorganic phosphate (Pi) into ATP. This process, called chemiosmosis, converts electrical energy into chemical energy stored in ATP's phosphate bonds. ATP then fuels various cellular activities, including metabolic reactions, substance transport, and mechanical work.3142
