Respuesta :
The answer is C. It is the electron transport chain reaction that produces water as one of it product. This type of reaction is the final and essential step in cell respiration. It's main function is to produce ATP but another product is also produced which is water. Brainliest?
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.
