Answer:
Transamination reaction:
Transmaination reaction may be defined as a type of chemical reaction that involves the transfer of an amino group to the another keto acid fort the formation of new amino acid. The non essential amino acid can be easily converted to essential amino acid by this transmination reaction.
This reaction is important for the important mteabolic pathways of the body. The cofactor required for the transamination reaction is pyridoxal-5'-phosphate. This cofactor also works as a derivative of vitamin B6. This cofactor is converted to pyridoxamine-5'-phosphate during the reaction.
It supports it by saying that there was once only one mammal but then it reproduced and since different places have different climates they adapted or evolved to the climate changing their form and shape.
