Active Transport

• 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.
