Question

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

Explanation:

• Conversion of pyruvic acid to Acetyl CoA: This occurs in the mitochondrial matrix and is part of aerobic respiration (requires oxygen).
• Conversion of pyruvic acid to lactic acid: This is lactic acid fermentation (anaerobic, no oxygen needed).
• Conversion of pyruvic acid to alcohol: This is alcoholic fermentation (anaerobic, no oxygen needed).
• Production of carbon dioxide in the citric acid cycle: The citric acid cycle is part of aerobic respiration (requires oxygen).
• Production of water in the electron transport chain: Oxygen is the final electron acceptor in the electron transport chain (requires oxygen).
• Production of pyruvic acid in glycolysis: Glycolysis is anaerobic (no oxygen needed).

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
