Cards (8)

  • What is the process of osmosis?
    Movement of water from high to low concentration
  • What is the main function of the cell membrane in transport?
    To allow certain substances to pass in and out of the cell
  • What is diffusion?
    The movement of molecules from high concentration to low concentration
  • What type of transport requires energy from the cell?
    Active transport
  • What is the main difference between active and passive transport?
    Active transport moves molecules against the concentration gradient
  • In which type of transport do molecules move with the concentration gradient?
    Diffusion
  • Which of the following molecules can pass through the cell membrane via simple diffusion?
    Oxygen
  • What is facilitated diffusion?
    The movement of molecules through a membrane protein down their concentration gradient
