Active Transport

Cards (7)

  • Does active transport move molecules down or against the concentration gradient?
    Against the concentration gradient
  • What is required for active transport to occur?
    Energy from the hydrolysis of ATP
  • Where is ATP produced?
    In the mitochondria
  • What type of proteins are involved in active transport?
    Carrier proteins
  • What happens to ATP during active transport?
    It is hydrolysed into ADP and phosphate to release energy
  • What is the main difference between active transport and facilitated diffusion?
    Active transport requires ATP but facillitated diffusion is passive
  • Define active transport.
    The movement of molecules and ions from an area of lower concentration to an area of higher concentration (against the concentration gradient) using ATP and carrier proteins.
