  • Carrier-mediated diffusion

    Carrier-mediated diffusion occurs when a protein changes shape to transport molecules across the membrane.

  • Osmosis

    Osmosis is the movement of water across a membrane from an area of low solute concentration to high solute concentration.

  • Difference between channels and carriers

    Channels act as tunnels allowing molecules to pass through, while carriers change shape to move molecules across the membrane.
