POINT!

酸素を使わないと、エネルギー代謝の効率は低い。

動画と音声での説明

酸素を使わないでエネルギー代謝を行うと、あまり効率はよくありません。栄養素にあった６つの（赤い線で示した）化学的エネルギーのうち、２つだけが取り出され、４つも分解産物に残っています

Energy metabolism without the use of oxygen is not so efficient. Out of the 6 chemical energy (shown in red lines) inside the nutrient, only 2 are removed and 4 remain in the degradation product.

Please note that the actual degradation is not simply removing connection, but also inserting H and OH, etc., this straight-forward illustration. To show the essential point of energy metabolism shows reaction that do not actually occur.
