Cotransport

According to the text that is used for the bio course I TA, auxin will enter cells via a cotransport protein and two protons, which will set-up the gradient required for the auxin to enter the cell. Once in the cell, auxin will disperse to the bottom of the cell and ...

... out like a sore thumb. Its probably pretty simple, but I dont have a clue as to how to go about it. here it is: Animal cells often use Na+ as a cotransport ion to regulate the internal concentration of H+. How many H+ can be transported for each Na+ that moves across the membrane? Use the following ...

... in the same direction? does glucose have an effect on the electron gradient? perhaps it's presence induces influx of Na+ ions, an effect of cotransport.

I think the effect of glucose on permeability has something to with its cotransport with sodium that creates an electrochemical gradient.
