Active Transport

• What type of process is active transport?

  Active
• What does active mean?

  Uses energy
• What is active transport?

  Movement of particles from low concentration to high concentration (against the gradient) across a partially permeable membrane which uses energy from respiration in the mitochondria
• How does active transport differ from passive transport?

  Active transport requires energy to move particles against the concentration gradient
• What type of membrane is involved in active transport?

  Partially permeable membrane
• What energy source is used for active transport?

  Energy from respiration in mitochondria
• Two differences between diffusion and active transport.

  Active transport uses energy and diffusion does not.

  Diffusion happens on the concentration gradient whereas active transport happen against it.
