Answer:
Oxygen
Explanation:
Oxygen is the last electron acceptor in the electron transport chain, which considers oxidative phosphorylation. Without oxygen, the electrons will be upheld, in the long run causing the electron transport chain to stop. This will make the results of glycolysis go through aging as opposed to going to the citrus extract cycle. Without oxygen, oxidative phosphorylation (the electron transport chain) is inconceivable, however substrate-level phosphorylation (glycolysis) proceeds.
