And when it rises high enough, we basically have insulin that is released by our beta cells. And what the insulin does is the opposite of what glucagon does. So insulin acts antagonistically with respect to the glucagon. So because we have a lot of glucose and amino acids and fatty acids inside our blood, let's suppose after we ate, what happens is the insulin causes our cells to become more permeable to glucose and amino acids and that causes the glucose to leave the blood plasma and into our cell. And we use the glucose to form glycogen in our liver cells, in our muscle cells. We uptake our amino acids and we form proteins.
