#Id: 6532

#Unit 7. System Physiology – Animal

The beta cells have a large number of glucose transporters that permit a rate of glucose influx that is proportional to the blood concentration in the physiological range

The entry of glucose into pancreatic β cells is mediated by the GLUT2 glucose transporter Because the Km for glucose of GLUT2 is 20 mM, a rise in extracellular glucose from 5 mM, causes a proportional increase in the rate of glucose entry
