WebApr 4, 2024 · Citric acid cycle, often referred to as “Krebs cycle” or “TCA cycle” is a mitochondrial metabolic cycle in which a (2C)acetyl unit from acetyl-S-CoA condenses with a (4C)oxaloacetate and generates a (6C)citrate molecule. An isomer of citrate is then decarboxylated, and the resulting (5C)a-Kgl undergoes oxidative decarboxylation to yield a WebOrnithine and lysine are the competitive inhibitors of arginine. The cycle for the overall reactions is given in Fig. 20.7.
