The best explanation for the dog's condition is that his mitochondria lack the transport protein that moves pyruvate across the outer mitochondrial membrane. This would prevent pyruvate, derived from glucose, from entering the mitochondria for further processing in the Krebs cycle, leading to an increased production of lactate as the cells resort to anaerobic metabolism. The dog's ability to use only fatty acids and amino acids suggests a specific issue with glucose metabolism, aligning with the inability to transport pyruvate into the mitochondria.
