Krebs Cycle (TCA Cycle): Complete Biochemistry Notes, Steps, and Energetics

Master the Krebs Cycle (also known as the Citric Acid Cycle or Tricarboxylic Acid Cycle) with these high-yield, perfectly structured biochemistry revision notes.

What this study guide includes:

• Introduction & Localization: Clear overview of the cycle's biological importance and its exact location inside the mitochondrial matrix.

• The Link Reaction: How Pyruvate from glycolysis is converted into Acetyl-CoA via the Pyruvate Dehydrogenase (PDH) complex.

• Step-by-Step Pathway: A complete breakdown of all 8 enzymatic reactions, from Citrate synthesis to Oxaloacetate regeneration.

• Energetics & Net Yield: Detailed counting of NADH, FADH2, and GTP/ATP molecules generated per turn and per glucose molecule.

• Regulation Checkpoints: Focus on the major regulatory enzymes (Isocitrate Dehydrogenase, alpha-Ketoglutarate Dehydrogenase).

• Amphibolic Nature: Explanation of how the cycle serves both catabolic (breaking down) and anabolic (building up) pathways.
