Oxaloacetate Metabolism

The video explores gluconeogenesis, focusing on the transport of oxaloacetate from the mitochondria to the cytosol. It explains the conversion of pyruvate to oxaloacetate, the role of malate as a shuttle, and the formation of phosphoenolpyruvate. Two pathways are discussed: one involving cytosolic PEP carboxykinase and another using mitochondrial PEP carboxykinase. The video concludes with a brief mention of glycolysis and gluconeogenesis regulation by phosphofructokinase 2.
