Describe two benefits of a cell carrying out anaerobic glycolysis. Be sure to include the following in your answer : pyruvate, electrons (in hydrogen atoms), oxygen, mitochondrion, Krebs cycle, ETS, and ATP
What will be an ideal response?
Glycolysis produces ATP in the cytosol and does not require oxygen. Therefore, when oxygen concentrations in the cell decrease below optimum, the cell can still synthesize ATP using energy extracted from glucose. Another advantage is that glycolysis provides substrates in the form of pyruvate and high-energy electrons that can be used within the mitochondria to generate more ATP. The pyruvate is modified into acetyl CoA, which enters the Krebs cycle; and high-energy electrons (within hydrogen atoms) that are taken out of glycolysis reactions can be used to power the electron transport system, which is important for oxidative phosphorylation within the mitochondrion.
