Aerobic (oxygen-using) metabolism can be defined as a biological process that typically involves the extraction of energy from any carbohydrate source such as amino acids, fatty acids, etc.

Basically, an aerobic metabolism of amino acid is a process that requires deamination.

Generally, proteins comprises of amino acids and it is responsible for maintaining the proper functioning of the body system.

Transamination can be defined as a biochemical process which typically involves the removal of amino groups from amino acids and transferring them to a ketoacid (amino acid without an amine group), so as to form new amino acids.

Basically, transamination is a reversible oxidation-reduction reaction that is responsible for the deamination of amino acids.
