Solution
The correct option is D Oxygen
ATP is produced during the process of oxidative phosphorylation in the mitochondria which is a part of aerobic respiration.
The electron transport chain plays an important role in this process. The electrons move through a series of electron donors and carriers that lead to the formation of a potential gradient.
This gradient helps in ATP synthesis. During this process, oxygen is reduced by the hydrogen from NADH and it finally accepts the electron in the chain.
Thus it is the terminal electron acceptor that results in the formation of water molecules. Thus the correct answer is option D.
