And so for that reason the Pyruvate is fed directly into the mitochondria. So we see that these cardiac muscle cells really utilize these high energy molecules because not only do the glucose molecules inside the cardiac muscle cell actually transform into Pyruvate and then go into the mitochondria. And not only are the glycogen storages used to produce the glucose six phosphate which ultimately form the ATP molecules, but in addition the lactate molecules produced by the other cells that undergo anaerobic respiration are also used to actually form these energy molecules. So we see that cardiac muscle cells can use lactate molecules to form the ATP energy molecules and so by doing that, they essentially create this additional source of energy and they also conserve the glucose molecules inside the bloodstream by conserving the glucose molecules by using less glucose molecules or more lactate molecules. That basically means other cells can basically use the glucose to carry out different types of different types of processes. Now that's basically the first place where the lactate ends up.
