  • ATP
    • Immediate source of energy
      • Plant/animal cells release energy from glucose (respiration)
      • Cell cant get energy directly from glucose
      • In respiration, energy released from glucose used to make ATP
      • ATP made from adenine combined with ribose sugar and three phosphate groups- nucleotide derivative, modified form of nucleotide
      • ATP diffuses to part of cell requiring energy
      • Energy in ATP stored in high energy bonds between phosphate groups. Released via hydrolysis
    • Production
      • When energy is required, ATP hydrolysed into ADP and Pi
      • Phosphate bond broken, energy released. Catalysed by ATP hydrolase
      • ATP hydrolysis coupled to other energy requiring reactions- energy released used directly rather than being lost as heat
      • Inorganic phosphate (Pi) can be added to another compound to increase reactivity
      • ATP re-synthesised in condensation reaction between ADP and Pi, during respiration/photosynthesis, catalysed by ATP synthesase
