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

Answer;

Electron transport chain

Explanation;

-Electron transport chain is the last stage of cellular respiration (aerobic), other stages being glycolysis and citric acid cycle.

-Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2. These electron carriers then donate electrons and protons to the electron carrier proteins of the electron transport chain. The final electron acceptor is oxygen. Together with oxygen, electrons and protons form molecules of water.
