One place in the EK book suggests glucose transport into the cell is via facilitated diffusion. Another place suggests it is brought into the cell via secondary active transport. Which one is right?
Also, if in active transport, ATP is used to "set up" a concentration gradient, does that mean the molecule is moving down its gradient after the ATP has been spent?
Thanks!
