Question

what are transamination and deamination and how do they allow for proteins to produce ATP?

Answer 1

ANSWER :

Both transamination and deamination process are essential for metabolism of proteins, occur at the same time, because during transamination the amino group from an amino acid transferred to another ketoacid with the enzymatic activity of transaminase, and on the other hand, deamination occurs in that amino acid from which amino group moved to new amino acid.

When most of the glucose (main energy substrate) in body (about 80-85%) runs out then body allows protein metabolism to produce ATP to meet the energy needs. During this process, proteins degrade into glutamate amino acid, and followed by converted to alpha ketogluterate via transamination and deamination process, and then enter to Kreb's cycle (step of cellular respiration) to produce ATP.
