Active transport is the movement of molecules up their concentration gradient , using energy. The concentration of most molecules inside a cell is different than the concentration of molecules in the surrounding environment.
The two carrier proteins on the left are using ATP to move sodium out of the cell against the concentration gradient. The proteins on the right are using secondary active transport to move potassium into the cell. Active transport is the movement of a substance across a membrane against its concentration gradient. This is usually to accumulate high concentrations of molecules that a cell needs, such as glucose or amino acids.
