Explanation / Answer

Answer:

1) What establishes the driving force for the glucose transport from the gut into the intestinal epithelial cells?

2) Glucose crosses into the blood by

3) On the cell membrane, the Na+ K+ ATPase pump transports 2K+ in for every 3Na+ that it transports out.

4) Which of the following statements correctly describes the properties of the enzymes x and z, graphed above?
