in the absence of oxygen muscle cells may convert pyruvic acid into what compound?
ethanol
pyruvic acid supplies energy to cells through the citric acid cycle (also known as the krebs cycle) when oxygen is present (aerobic respiration), and alternatively ferments to produce lactate when oxygen is lacking (lactic acid fermentation).
