NEITHER |
Homework Answers
In this case, once insulin binds to the insulin receptor, transport vesicles will mobilize the GLUT4 directly to the cellular membrane in order to increase the intake of glucose. So, the correct answer is both

State rational for your answer: 6) In unstimulated muscle cells, the glucose transporter Glut4 is present in the membrane of endosomes. Upon stimulation of these cells with insulin, the endosomes fuse with the plasma membrane, thereby depositing Glut4 in the plasma membrane, where it serves to transport glucose into the cells. In order for insulin to elicit this change in Glut4 localization, insulin...

The binding definitive of cell surface receptor proteins is described by a parameter K0.5, which is analogous to KM of an enzyme, and it represent the concentration of ligand where the protein is 50% saturated. Brain cells have a glucose binding receptor called GLUT3 and muscle cells have a similar receptor called GLUT4 on their membranes. Will the K0.5 of brain GLUT3 be higher or lower than the K0.5 of muscle GLUT4? What is the physiological significance of this difference?

Question 12 10 pts Insulin is released when blood glucose levels are . This causes increased absorption of glucose into cells by the transporter. This transporter has a Ky which allows rapid glucose uptake. Insulin promotes activity of to make glycogen for energy storage. Adipose tissues also increase energy storage by making from fatty acids.
