| Question | Answer |
|---|---|
| Define oxidoreductases | Its a catalyze oxidation-reduction reaction in which there is a transfer of electrons from the reductant (electron donor) too the oxidant (electron acceptor) |
| Define transferases | It catalyze the transfer of a specific functional group |
| Define hydrolases | It catalyzes the cleavage of a single bonds by the addition of water |
| Define lyases | - It catalyzes the non-hydrolytic and non-oxidative cleavage of single bonds - Often forming double bonds through elimination reactions |
| Define isomerases | It catalyzes the movement of a group from one position to another within the same molecule without altering the atomic composition of that molecule |
| Define ligases | It catalyzes the formation of new C-C, C-O, C-N, C-S, and other single bonds by coupling that formation to the hydrolysis of nucleoside triphosphate |
