Question

Quizplus · Accepted Answer

Most of the water in this reaction is produced during the electron transport chain, which is the final stage of cellular respiration. Here, electrons are transferred along a series of proteins, which pumps protons (H+) out of the mitochondrial matrix. Oxygen (O2) then accepts these electrons and combines with protons to form water (H2O).
