Which of the following categories of enzyme classification are correctly matched?
| EC 1 | Oxidoreductases: catalyze oxidation/reduction reactions |
| EC 2 | Hydrolases: catalyze the hydrolysis of various bonds |
| EC 3 | Transferases: transfer a functional group (e.g. a methyl or phosphate group) |
| EC 4 | Lyases: cleave various bonds by means other than hydrolysis and oxidation |
| EC 5 | Isomerases: catalyze isomerization changes within a single molecule |
| EC 6 | Ligases: join two molecules with covalent bonds. |
