In the fermentation pathways, NADH transfers electrons to pyruvate.  In this process, NADH is oxidized and pyruvate is reduced.      True   False If a sprinter runs faster than her muscle mitochondria can produce ATP,  she will eventually begin to feel a burning sensation in her leg muscles.  The cause of the burning is that she cannot breath fast enough to provide her mitochondria with the oxygen necessary for it to continue to produce ATP at the rate the ATP is being used.  As a result, the pyruvate enters a fermentation pathway, which causes burning because of the alcohol produced in her muscle cells.           True   False
