The real need to remember most of the important reactions

Amino acid catabolism to produce glutamate in presence of alpha-KG catalysed by enzyme aminotransferase which undergoes reversible reaction to produce alpha-KG & NH4+ in presence of enzyme GDH & NAD...

Partial catabolism reduces to alanine with production of ATP in presence of malic enzyme and ALT with no internal pollution of NH4+; Malate transformation in presence of pyruvate produces alanine & alpha-KG

Constant supply of pyruvate to produce alpha-KG to sustain forward reaction of partial amino acid catabolism; excess alpha-KG as substrate transforming to glutamate will produce NH4+ causing accumulation of toxic

I will forget the above mentioned in just 5 mins...
