During which process is water produced? alcohol fermentation acetyl CoA formation electron transport chain citric acid cycle

Water is produced during the electron transport chain when oxygen acts as the final electron acceptor, combining with electrons and protons to form water. This crucial step is part of cellular respiration and helps maintain the flow of electrons through the chain. Additionally, in the citric acid cycle, carbon dioxide is released as a byproduct, but the cycle itself doesn't produce water. The overall cellular respiration process, which encompasses glycolysis, the citric acid cycle, and the electron transport chain, focuses on maximizing energy production while generating vital molecules like water.
