Which of the following transporters contributes to the transcellular transport of glucose?
| A) All of the above |
| B) C&D only |
| C) Glucose uniporter |
| D) Na+/ glucose symporter |
| E) Na+/K+ pump |
Homework Answers
Transport of glucose across cells occurs by both uniporters and NA+/glucose symporter i.e. co4ect option is option D.
GLUT is the kind of uniporter transport protein that does the function glucose transport distributed throughout body. Where as recently discovered is the sodium-dependent cotransport of glucose happens in intestinal absorption.

1. Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na-glucose symporter. Recall that the Na concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na' ions into the cell to the "uphill" transport of glucose into the cell. (opts) a. If the Na concentration outside the cell ([Na Jou) is 161 mM...
