D) lactic acid in glycolysis.

Question

Quizplus · Accepted Answer

In aerobic respiration, oxygen serves as the final electron acceptor at the end of the electron transport chain. During this process, electrons and hydrogen ions are transferred from NADH and FADH2 to a series of electron carriers, ultimately leading to the production of ATP. Oxygen combines with these electrons and hydrogen ions to form water, which is then excreted from the cell.
