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

How Is Oxaloacetate Made In The Krebs Cycle?

How Is Oxaloacetate Made In The Krebs Cycle? The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate) (see Figure above). This produces citric acid, which has six carbonatoms. This is why the Krebs cycle is also called the citric acid cycle. How is oxaloacetate produced? The beginning of
