The α-amino group of many amino acids is transferred to α-ketoglutarate to form glutamate, which is then oxidatively deaminated to yield ammonium ion (NH4+).
Passive transport:
For simple diffusion = fatty acids, amino acids, steroid hormones (because they’re non-polar)
Facilitated diffusion = N2 and Cl-
