active transport

• Active transport


  1. Movement of particles from low to high concentration

  2. Against concentration gradient

  3. Using energy (ATP)

  4. From cell respiration

  5. Moves protein pump
• Use of active transport

  • Absorption of sugar in small intestine
  • Absorption of mineral ions by plant roots
• Absorption of sugar in small intestine

  Active transport allows all the sugar to be absorbed from food, even if it needs to be moved against the concentration gradient
• Absorption of mineral ions by plant roots

  Ions are found in low concentrations in soil, so active transport can be used to absorb minerals for growth
