Major contribution towards gluconeogenesis: (A) Ketones, (B) Alanine, (C) Lactate, (D) Glycine
Answer is B. Alanine dominates among transpoed amino acid. It is postulated that pyruvate in skeletal muscle undergo transamination to produce alanine. Alanine is transpoed to liver and used for gluconeogenesis.This cycle is referred to as glucose-alanine cycle Ref: satyanarayana 4th edition , pg: 262
