RESUMO
The capacity of mitochondria isolated from livers of 5-day-old piglets to convert pyruvate to phosphoenolpyruvate, malate and citrate has been investigated. These mitochondria have a large capacity to flux pyruvate through the pyruvate carboxylase reaction causing an accumulation of malate, citrate and phosphoenolpyruvate. As much as 70% of the pyruvate utilized during state 3 respiration can flux through the pyruvate carboxylase reaction. The data indicate that phosphoenolpyruvate from mitochondria can contribute a significant fraction of the carbon skeletons of pyruvate converted to glucose by piglet liver (estimated to be 30%).
