In active transport, molecules move against a concentration gradient, therefore

  • A molecules move from a region of low concentration to a region of high concentration
  • B molecules move from a region of high concentration to a region of low concentration
  • C the concentration gradient has little effect on the movement of molecules
  • D molecules force their way through special channels
