ways of transport

• What are the types of transport in cells?

  • Passive Transport
  • Simple Diffusion
  • Facilitated Diffusion
  • Osmosis
  • Active Transport
  • Active Transport
  • Active Cotransport
• What is simple diffusion?

  Simple diffusion is the movement of particles from high to low concentration down the concentration gradient.
• What factors affect the rate of simple diffusion?

  The rate is affected by temperature, size of molecules, and steepness of the gradient.
• What is facilitated diffusion?


  Facilitated diffusion is the movement of particles from high to low concentration using a channel protein.
• What is osmosis?


  Osmosis is the movement of water from low solute concentration to high solute concentration through a semipermeable membrane.
• What is active transport?

  Active transport is the movement of particles up a concentration gradient, requiring ATP and a protein carrier.
