    Study Notes

    Citric Acid Cycle

    • Also known as the Krebs cycle or tricarboxylic acid (TCA) cycle

    Acetyl-CoA

    • Primary source: breakdown of carbohydrates, fats, and proteins

    Reducing Agents

    • Citric acid cycle produces NADH and FADH2 as reducing agents

    Acetate in Citric Acid Cycle

    • Fate: converted to acetyl-CoA, which enters the citric acid cycle
