How Is Oxaloacetate Regenerated To Complete The Tca Cycle?

How Is Oxaloacetate Regenerated To Complete The Tca Cycle? The citric acid cycle utilizes mitochondrial enzymes. The first step is fusion of the acetyl group of acetyl-CoA with oxaloacetate, catalyzed by citrate synthase. CoA-SH and heat are released and citrate is produced. Citrate is isomerized by dehydration and rehydration to isocitrate. What is regenerated in
