How Is Fumarate From Urea Cycle Transported To Tca Cycle?

How Is Fumarate From Urea Cycle Transported To Tca Cycle? Fumarate is then free to join the citric acid cycle, while arginine is degraded to urea and ornithine via the arginase enzyme. Ornithine is then transported back into the mitochondria via the ornithine-citrulline transporter, where the cycle can begin again. What connects urea cycle to
