    Solution :

So deamination is the removal of amino group \[(-N{{H}_{2}})\] from carboxyl group with formation of ammonia and keto group. Glutamic acid m-keto glutaric acid \[+N{{H}_{3}}\] Transamination is the transfer of an amino acid from an alpha-amino acid to an alpha-keto acid. Excretion is removal of waste material from body.
