    Study Notes

    Citric Acid Cycle

    • The citric acid cycle is also known as the Krebs cycle or tricarboxylic acid (TCA) cycle.
    • The main purpose of the citric acid cycle is to generate energy for the cell through the breakdown of carbohydrates, fats, and proteins.

    Cellular Respiration

    • The citric acid cycle is used in aerobic respiration to generate energy.

    Precursors and Metabolites

    • The citric acid cycle provides precursors for the synthesis of amino acids, choline, and other biomolecules.
    • It is not necessary for metabolites to follow only one specific route in the citric acid cycle, as the cycle is flexible and can accommodate different metabolic pathways.
