. Skeletal muscle cells produce glucose carriers (GLUT 4 transporters). Rather then having these transporters continually on their surface, they store them inside vesicles within the cell. During exercise (muscular contraction), these vesicles fuse with the plasma membrane of the cell, inserting the transporters into the membrane. This allows glucose to enter the cell by passive transport. Which of the factors that affect simple diffusion has been altered in this example?

6) In unstimulated muscle cells, the glucose transporter Glute 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 Glute localization, insulin must bind to its receptor, present in the plasma membrane of some cells. To determine if a stem cell line can be...

Glucose is transported into the intestinal cells via cotransport with sodium. Assume the following conditions: Temp = 37oC Sodium (in) = 12.0 mM Sodium (out) = 145 mM Glucose (out) =28 μM ΔΨ = -72mV (inside is negative) a. What is the ΔG for sodium transport? b. What is the upper limit of glucose transport?

The Na –glucose symport system of
intestinal epithelial cells couples the \"downhill\" transport of
two Na ions into the cell to the \"uphill\" transport of glucose,
pumping glucose into the cell against its concentration gradient.
If the Na concentration outside the cell ([Na ]out) is 155 mM and
that inside the cell ([Na ]in) is 17.0 mM, and the cell potential
is -53.0 mV (inside negative), calculate the maximum ratio of
[glucose]in to [glucose]out that could theoretically be produced if...

1) Glucose enters human enterocytes (intestinal epithelial cells) against its concentration gradient. A Na+ ion enters the cell with each glucose molecule, and while the glucose transporter does not hydrolyze ATP, it depends on a pre-existing gradient of Na+ ions that is created by the Na+/K+ ATPase. This is an example of ____________. A. primary active uniport B. secondary active antiport C. primary active symport D. secondary active symport 2) Which statement is FALSE? A. Acetyl CoA is oxidized to...
