Active transport involves a molecule binding to a carrier protein, ATP hydrolysis providing energy for a shape change, and the release of the molecule and phosphate group.

| Front | Process of active transport 2.1.5(d) |
|---|---|
| Back | - molecule binds to receptors on CP outside cell - ATP binds to CP and hydrolysed into ADP and po4 inside cell - binding of PO4 causes change in shape of CP, which opens to inside of cell - molecule released inside cell, aswell as PO4 which recombines with ADP forming ATP - CP returns to original shape |
