    Study Notes

    Metabolism

    • Metabolism refers to the collective biochemical reactions that occur within an organism to maintain life, including the breakdown and synthesis of organic molecules.

    Metabolites

    • Metabolites are the intermediate products of metabolism, formed during the breakdown or synthesis of organic molecules.

    Anabolism and Catabolism

    • Anabolism is the process of building or synthesizing molecules, requiring energy and resulting in the growth and repair of cells.
    • Catabolism is the process of breaking down molecules, releasing energy and resulting in the degradation of cells.
    • Anabolism and catabolism are complementary processes, often occurring simultaneously, and are necessary for maintaining cellular homeostasis.

    Enzymes in Metabolic Pathways

    • Enzymes are biological molecules, typically proteins, that catalyze specific chemical reactions in metabolic pathways, increasing reaction rates and efficiency.
    • Enzymes act as biological catalysts, allowing metabolic reactions to occur at a rate necessary to sustain life.

    Catabolic Pathways

    • Catabolic pathways are metabolic reactions that break down complex molecules, such as carbohydrates, proteins, and fats, into simpler compounds, releasing energy in the form of ATP.
    • Catabolic pathways are essential for generating energy and providing building blocks for anabolic reactions.
