Now, we see that for our NADH molecules that are formed inside the mitochondrial matrix and this includes the nadhs formed in pyruvate decarboxylation and the citric acid cycle. For every one NADH molecule formed we form three ATP molecules. So when we oxidize one NADH on complex number one we form three ATPs. Now, for one NADH that is formed in glycolysis which takes place in the cytoplasm of the cell a net of two ATP molecules are produced. And that's because a single ATP must be used to actually transport that NADH from the location weglisis takes place the cytoplasm into the mitochondrial matrix where our electron transport chain is found. Now, what about our Fadh two?
