Resource summary

ATP
  1. Adenosine Triphosphate
    1. Structure
      1. A single molecule of ATP is a Nucleotide
        1. molecule of Ribose
          1. Pentose sugar
          2. a molecule of adenine
            1. 3 phosphate Groups
              1. it does not have 3 phosphates attached! The proper description is phosphate groups
          3. Hydrolysis of ATP
            1. ATP contains much energy but that energy needs to be released
              1. in the presence of water
                1. it becomes hydrolysed.
                  1. The end phosphate group is hydrolysed
                    1. as it breaks from the main molecule
                      1. free energy is released
                      2. The inorganic phosphate released during the hydrolysis of ATP can be used to phosphorylate other compounds
                        1. often making them more reactive
                      3. The hydrolysis of ATP can be coupled to energy-requiring reactions within cells
                    2. to adenosine diphosphate (ADP)
                      1. and an inorganic phosphate group (Pi)
                      2. catalysed
                        1. by the enzyme ATP Hydrolase
                      3. Resynthesis of ATP
                        1. Condensation of ADP and Pi
                          1. elimination of a small molecule
                            1. like H₂O
