ATP

• How is ATP made?

  . Formed via anaerobic or aerobic respiration

  . Mitochondria converts chemical energy stored in carbohydrates and bonds into ATP . Can be formed via ADP + Pi
• Structure


  . Adenine base

  . Ribose sugar

  . Tri-phosphate group

  . Same structure as a nucleotide monomer of RNA but 3 phosphate groups instead of 1 
• Equation 


  . ADP is ATP with 2 phosphate groups instead of 3

  . ADP + Pi -> ATP

  . Pi is an inorganic P phosphate group the (i) shows it is inorganic
• Function

  . Short term storage + use of energy

  . The phosphate group is easily accessible and once the bond is broken there is a small release of energy
