Now, what happens is, because we have plenty of glucose and amino acids floating around inside our bloodstream, what insulin does is it causes the cell membrane to become more permeable to amino acids and to glucose. And now glucose and amino acids go into our cells, into liver cells and muscle cells. And those cells basically use the amino acids to form protein and they use the glucose to form our glycogen. Now, what insulin also does is it causes our fat cells to take up glycerol and fatty acids and to form our triglyceride. So what our insulin ultimately aims to do is to basically decrease the concentration of our glucose found inside our blood. So these two hormones are essential in controlling the concentration of glucose and amino acids and fatty acids found inside our blood.
