Which of the following statements correctly describe fermentation? Select ALL that are correct: - Produces carbon dioxide - The method plants and animals rely on to produce a large amount of ATP - Glycolysis is one of the steps - Oxygen is the final electron acceptor - Approximately 30 ATP molecules are produced - It is a redox reaction - Produces heat - Requires oxygen - Citric Acid Cycle is one of the steps - Produces alcohol - Oxidative phosphorylation is one of the steps - Occurs in the cytosol - Pyruvate Oxidation is one of the steps - The method yeast use to produce ATP - Requires mitochondria
