So let's examine what happens to our glycerol. The glycerol is basically broken down into a molecule known as PGAL or glyceroaldehyde three phosphate, which is basically an intermediate within our glycolysis cycle. So our glycerol ultimately ends up in glycolysis. So our glycerol goes into glycolysis and we use glycerol to form pyruvate molecules, which then end up in the mitochondrial matrix where they are fed into our decarboxylation reaction, producing acetyl coenzyme A, which goes into the crept cycle and eventually on the electron transport chain to produce our ATP molecules. Now, what about the fatty acids? So the pathway that is followed by the fatty acids is slightly different.
