Now if an H is picked up by this, that is what we call lactic acid. So lactate is the conjugate base of lactic acid. So we see that the lactate dehydrogenase catalyze the transfer of the hydrad group and so ultimately we regenerate that NAD plus. And again we have to multiply this by two because we have two pyruvate molecules coming in from the process of glycolysis. And again, if we sum up all those reactions in glycolysis and this reaction, this is the net equation that we get. And notice it's slightly different than this equation here because here we produce carbon dioxide, but here we don't have carbon dioxide and we also don't have the two H plus.
