Which set lists the three common alternative names for the Krebs cycle?

• A. TCA cycle, Tricarboxylic Acid Cycle, Citric Acid cycle
• B. Krebs cycle
• C. Citric Acid Cycle
• D. Electron transport chain

Answer: (A)

The main concept here is knowing the different names used for the Krebs cycle. The three most common terms that refer to the same sequence of reactions are the TCA cycle, Tricarboxylic Acid Cycle, and Citric Acid Cycle. This set is the best answer because it includes all widely used names that describe the same pathway, reflecting both the abbreviation (TCA), the formal descriptive name (Tricarboxylic Acid Cycle), and the substrate-based name (Citric Acid Cycle). The term Krebs cycle is also used in practice, but it doesn’t list the other two alternative names, and Electron transport chain is a different part of cellular respiration entirely, not an alternative name for the Krebs cycle.
