Which processes require oxygen? Check all that apply.

conversion of pyruvic acid to Acetyl CoA
conversion of pyruvic acid to lactic acid
conversion of pyruvic acid to alcohol
production of carbon dioxide in the citric acid cycle
production of water in the electron transport chain
production of pyruvic acid in glycolysis

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 :

The processes can be explained as:

Therefore, in ETC and conversion of pyruvic requires oxygen.

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.
