Question

In many animal cells, the uptake of glucose into the cell occurs by a cotransport mechanism, in which glucose is cotransported with na+ ions.

Answer 1

Answer:
outside cell:
[Na+] high
[glucose] low
transporter: glucose and Na+ go down
inside cell:
[Na+] low
[glucose] high
1. Na+ moves down its electrochemical gradient.
2. Glucose moves against its concentration gradient.
