And once this is activated, we'll produce plenty of acetyl coenzyme A molecules needed to produce ACP, so we can continue running away from that scary animal, our bear. Now, insulin. So following a meal that's let's suppose rich in carbohydrates, we're going to see that our blood glucose level will rise and liver cells and other cells of the body will try to maintain that glucose level. So liver cells will respond to insulin by basically activating that phosphatase and activating this Pyruvate dehydrogynase complex. So that ultimately all those glucose molecules that are absorbed by the liver cells can be transformed into acetyl coenzyme A. And we can produce those ATP molecules.
