ATP
Universal energy composed of nitrogenous base, pentose sugar and 3 phosphate groups.
Hydrolysis
Breaks chemical bond between two molecules, involves the use of a water molecule
ADP
Product of hydrolysis of ATP. Releases a phosphate ion, therefore releasing energy
Phosphorylation
Reattaching of phosphate group to ADP. due to ADP being instable and not a good long term energy source
