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

Answer

Brief Explanations:

  1. Conversion of pyruvic acid to Acetyl - CoA occurs in the mitochondria and is part of aerobic respiration, requiring oxygen.
  2. Conversion of pyruvic acid to lactic acid is anaerobic fermentation and does not require oxygen.
  3. Conversion of pyruvic acid to alcohol is also anaerobic fermentation and does not require oxygen.
  4. The citric - acid cycle is part of aerobic respiration and the production of carbon dioxide in it requires oxygen as it is part of a series of reactions that rely on the presence of oxygen for the complete oxidation of fuels.
  5. In the electron - transport chain, oxygen acts as the final electron acceptor, and the production of water occurs as a result of this process which requires oxygen.
  6. Glycolysis is an anaerobic process and the production of pyruvic acid in it does not require oxygen.

Answer:

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