  • What are the two types of diffusion

    Simple and facilitated

  • Protein pump

    Use energy from the cell to change shape and pump the molecule. Works in both directions and is faster than diffusion

  • Active transport process

    Molecule/ion combines with carrier protein on outside of membrane. ATP transfers a phosphate group to carrier protein on inside of membrane. Carrier protein changes shape and carries the molecule across the membrane. Molecule is then released. Phosphate is released from carrier protein and recombines with ADP-ATP. Carrier protein then returns to original shape
