Substrate of gluconeogenesis

Web8 May 2024 · The major substrates of gluconeogenesis are lactate, glycerol, and glucogenic amino acids. Lactate is a product of anaerobic glycolysis. When oxygen is limited (such as during vigorous exercise or in low perfusion states) cells must perform anaerobic glycolysis to produce ATP. Cells that lack mitochondria (e.g., erythrocytes) cannot perform ...
