  • What are three mechanisms of carrier-mediated transport?
    The three mechanisms of carrier-mediated transport are uniporters, symporters, and antiporters.
  • What is the difference in energy source between primary and secondary active transport?
    Energy source is a difference; primary active transport uses ATP directly, while secondary active transport uses the energy from the electrochemical gradient.
  • What allows ions to flow down their electrochemical gradient across the membrane?
    Passive transport allows ions to flow down their electrochemical gradient without the use of energy.
  • Which membrane movement process is not passive?
    Active transport is not a passive process as it requires energy.
  • What is an example of a passive membrane transport process?
    Facilitated diffusion is an example of a passive job.
  • How do ions typically move across the plasma membrane during passive transport?
    Ions move from high to low concentration without energy.
  • Leak channels allow the movement of potassium and sodium ions by what type of membrane transport?
    Leak channels allow the movement of ions through passive transport, following their concentration gradient.
  • What is the primary energy source for active transport?
    The primary energy source for active transport is ATP.
  • How do symporters function in membrane transport?
    Symporters co-transport two or more molecules in the same direction across the membrane.
  • What distinguishes antiporters from symporters?
    Antiporters transport molecules in opposite directions, while symporters transport them in the same direction.
