Which term is not synonymous with the Krebs cycle?

• A. Citric Acid Cycle
• B. Aerobic Pathway
• C. Glycolysis
• D. Tricarboxylic Acid Cycle

Answer: (C)

The main idea is that the Krebs cycle is a specific mitochondrial sequence in aerobic respiration with a couple of standard names, while glycolysis is a different pathway altogether. The Krebs cycle is also called the citric acid cycle and the tricarboxylic acid cycle, since citrate is formed early in the cycle and citrate has three carboxyl groups. It takes place in the mitochondria and oxidizes acetyl-CoA to CO2, generating NADH and FADH2 for the electron transport chain. The term aerobic pathway refers to the oxygen-using set of reactions that ultimately produce energy, including the Krebs cycle and oxidative phosphorylation, but it isn’t a name for the Krebs cycle itself. Glycolysis, by contrast, occurs in the cytosol, converts glucose to pyruvate, yields ATP and NADH, and does not constitute the Krebs cycle. So glycolysis is not synonymous with the Krebs cycle.
