Sodium concentrations are higher outside and glucose concentrations are higher inside the cell. Using the same membrane protein for Na + and glucose transport, what is it called when a Na + electrochemical gradient is used to drive glucose transport into the cell against its concentration gradient?

It is called active transport when glucose is transported into the cell against its concentration gradient.

Explanation:

The cell must use energy to transport a substance against an electrochemical or concentration gradient. Active transport mechanisms spend energy in the form of ATP to maintain the correct concentrations of ions and molecules in living cells.
