In active transport, energy is used to move a solute against its concentration gradient.

In active transport, energy is used to move a solute against its concentration gradient.

Figure 5.13 Primary Active Transport: The Sodium–Potassium Pump. In active transport, energy is used to move a solute against its concentration gradient. For each molecule of ATP used, 2 K + are pumped into the cell and 3 Na + are pumped out of the cell. K +. Outside of cell. Sodium–
