Oxygen is the most vital element that is required exclusively by all animals, plants and some type of microorganisms. It has an atomic number of 8 and is represented with the alphabet O.

The cycles that need oxygen are :

Option 1. The transformation of pyruvic acid to acetyl-CoA.Option 5. The formation of water in the electron transport chain.

The processes can be explained as:

Oxygen is crucial for metabolic operations in the cells. The organisms utilizing oxygen for processes are called aerobic.The procedure of transforming pyruvic to Acetyl coenzyme A requires oxygen. Pyruvate is the outcome of the glycolysis cycle of cellular respiration. In the presence of oxygen molecules, cellular respiration moves forward towards the TCA cycle to produce Acetyl CoA.In ETC electrons transfer occurs from one complex to another in the mitochondrial membrane that needs oxygen as the final acceptor that produces the water molecule.

Therefore, in ETC and conversion of pyruvic requires oxygen.

Answer from: nelly88

This is a cellular respiration question, related to biology.

Some processes in our bodies require the use oxygen, others do not.

In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.

If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Water in the ETC is formed in the process when NADH and FADH2 are converted to molecular oxygen due to the electron transporters. The protons are then pumped and oxygen is reduced to form H2O.
