ATP

• ATP - adenine tri phosphate

  is a nucleotide derivative, its an immediate source of energy for biological processes

  metabolc reactions in cells must have a constant, steady supply of ATP
• ATP is made during respiration from ADP + Pi by a condensation reaction using the enzyme ATP synthase
• ATP can be hydrolysed into ADP + Pi using the enzyme ATP hydrolase, this releases a small amount of energy
• energy is stored between the bonds between the 3 phosphate groups.

  these bonds are unstable so easily broken for an immediate source of energy
• the energy stores are not long term, they produce a few seconds supply

  its an immediate source of small amounts of energy

  it cant be stored and is continuously produced in the mitochondria

  cells with high energy requirements have more mitochondria
