So it's not as low as these two and it's not as high as this. And actually, these glute four membrane proteins are sensitive to the insulin. So the insulin is able to actually stimulate these muscle cells and adipose tissue cells, so fat cells to express more of these glute four on the membrane of these cells. And once they express more of these glute four, they're able to actually uptake all those glucose molecules from the blood plasma following the ingestion of that carbohydrate rich meal. So glute four are found in the cells of muscle and adipose tissue, they have a km value, the maclus constant of about five millimolar and respond to insulin. And following food ingestion, muscle and fat cells express many more glute four membrane proteins to assist with glucose uptake.
