WebWhen does the glucose alanine cycle occur? When amino acids are being broken down in muscle. What happens to muscle pyruvate in the glucose alanine cycle? The liver converts alanine into pyruvate then to glucose. The glucose is released into blood and back into the muscle cell. Which reactions produce NH4+ as a byproduct? Valine ---> succinyl CoA. WebSep 23, 2024 · The glucose-alanine cycle represents a critical link between carbohydrate and amino acid metabolism and comprises a series of reactions in which pyruvate, derived mostly from intramyocellular glycolysis, is transaminated with ammonia, derived from muscle protein catabolism, to form l -alanine ( 1, 2 ).
