So in stage one, these triglycerides are actually broken down and mobilized into their fatty acid and glycerol form. Once that takes place, the fatty acids are released into the bloodstream and the bloodstream carries these molecules of fatty acids to their target cell. Once the fatty acid makes its way into the cytoplasm of that target cell, that's when stage B actually takes place. And in stage B, these fatty acids are activated, they're made more reactive and then they're transported into the matrix of the mitochondria. And that's when stage C begins. In stage C, those fatty acids are broken down in the matrix of the mitochondria into acetyl coenzyme A molecules.
