Refer to the given reaction
`alpha`-Ketoglutaric acid `+NH_(4)^(+)+NADPHunderset("dehydrogenase")overset("Glutamate")to"Glutamate"+H_(2)O+NADP` is represents

Options

A. oxidative amination
B. reductive amination
C. transamination
D. deamination

Answer

B

Explanation

The given reaction shows reductive amonation. In the presence of dehydrogenase (e.g., glutamate dehydrogenase, aspartate dehydrogenase) and a reduced coenzyme (NADH or NADPH), ammonia can directly combine with a keto organic acid like `alpha`- ketoglutaric acid or oxaloacetic acid to form amino acids.
