Which of the following best describes how fermentation of pyruvate to lactic acid facilitates the production of ATP in the absence of oxygen?

It provides  for continued glycolysis

It lowers the pH of the cytosol, increasing the efficiency of ATP synthase

It provides NADH for continued glycolysis

It removes pyruvate, shifting the equilibrium favorably toward the forward reactions of glycolysis

It provides lactic acid, which can phosphorylate ADP via substrate-level phosphorylation
