Chapter 26, Problem 26.72EP

Interpretation Introduction

Interpretation: To explain the relationship between the urea cycle and the citric acid cycle.

Concept introduction: A urea cycle is a cyclic biochemical pathway that involves the production of urea using ammonium ions and aspartate molecules as nitrogen sources. The desired product of the urea cycle is urea.

The citric acid cycle is a series of eight chemical reactions used to release energy by all aerobic organisms. The acetyl part of $\text{acetyl CoA}$ is oxidized with the release of ATP and carbon dioxide.
