active transport

• What is active transport?


  The movement of molecules against there concentraion gradient from a lower concentration to a higher concentration
• Does it require energy from the cell?


  yes.
• Active transport always takes place across..?

  a membrane
• What does the membrane contain that diffusions membrane doesnt?

  special proteins
• What do the special proteins in the membrane do?

  Transfer the molecules from one side of the membrane to the other
• What is the energy called?

  Cellular respiration
• What is cellular respiration?


  Process that happens in the mitrochondria that breaks done gluclose to release energy
• What is cellular respiration responsible for?


  all the energy the cell uses and stores it in ATP
• Where is active transport used?

  Root hair cells - have a higher conc inside the cell than outiside the cell so absorbs the mineral ions outside of the cell through active transport
