WebNov 3, 2024 · The reaction is catalyzed by pyruvate kinase and produces pyruvate. The two phosphorylation reactions are also called priming reactions, since they 'activate' the molecules for the... WebThe pyruvate produced can proceed to be catabolized or converted into the amino acid alanine. If no more energy is needed and alanine is in adequate supply, the enzyme is inhibited. The enzyme’s activity is increased when fructose-1,6-bisphosphate levels increase.
