Electron Transport Chain

	1) Glycolysis
	2) Intermediate Step
	3) TCA Cycle
	4) Electron Transport Chain

Solution

Glycolysis- Breakdown of sugar into two molecules of pyruvate with the release of energy.It doesn\'t need oxygen and is an anaerobic process. Intermediate step: Pyruvate oxidation into acetyl co A, only when oxygen is available.Otherwise, the process turns into the anaerobic process. TCA cycle- In this process, acetyl coenzyme A is converted into carbon dioxide molecules and doesn\'t directly need oxygen but happens only when the oxygen is available. ETC- Electron transport chain needs molecular oxygen as an electron acceptor and can be called as an aerobic process. Except for Glycolysis all the other processes are directly or indirectly they are all aerobic.
