Krebs Cycle (TCA): Steps and Significance · NCERT Biology

The Krebs cycle is also referred to as the 'Amphibolic Pathway' because it is involved in:

  1. Only catabolism (breakdown)
  2. Only anabolism (synthesis)
  3. Both catabolism and anabolism
  4. Both aerobic and anaerobic respiration
Show answer and explanation

Correct answer: Both catabolism and anabolism

It is catabolic because it breaks down acetyl groups to CO2, and anabolic because many of its intermediates (like alpha-ketoglutarate or OAA) are withdrawn for the synthesis of amino acids and other biomolecules.
