| Questão | Responda |
| GLUT1- Role | Constituative, responsible for basal uptake |
| GLUT1- Location | Almost every tissue |
| GLUT1- Glucose Affinity | 2.5-8mM |
| GLUT2- Role | Prevents entry of glucose into certain cells to preserve it for when necessary |
| GLUT2- Location | Liver and pancreatic B cells |
| GLUT2- Glucose Affinity | Low, at 15-20mM, but very high uptake in this range |
| GLUT2- Role in Liver | Allows glucose entry for storage when blood glucose levels are high enough |
| GLUT2- Role in Pancreas | When glucose is high enough, enters beta cells and signals insulin release |
| GLUT3- Role | Compliment GLUT1 uptake in highly active tissues |
| GLUT3- Location | Brain |
| GLUT4- Role | Basal insulin uptake (but is most effected by insulin) |
| GLUT4- Location | Skeletal muscle |
| GLUT4- Glucose Affinity | 5mM, but this changes with insulin secretion |
| GLUT5- Role | Fructose transporter |
| GLUT5- Location | Found in the small intestine |
