    Study Notes

    Metabolic Reactions

    • Metabolic reactions are biochemical processes in living organisms that convert substrates into products.
    • They are essential for maintaining homeostasis and supporting life functions.

    Property of Enzymes

    • Enzymes are biological catalysts that accelerate metabolic reactions without being consumed.
    • They have an active site that specifically binds to substrates, enabling reactions to occur more efficiently.

    Primary Function of Metabolism

    • The primary function of metabolism is to provide energy and building blocks for cellular processes.
    • Metabolism is divided into two categories: catabolism (breaking down molecules for energy) and anabolism (building complex molecules from simpler ones).

    Specific Conditions for Enzyme Function

    • Enzymes require specific conditions such as optimal temperature and pH to maintain their activity.
    • Deviations from these conditions can lead to decreased enzyme activity or denaturation.

    Role of Enzymes in Metabolic Reactions

    • Enzymes lower the activation energy required for metabolic reactions, facilitating faster biochemical processes.
    • They play a crucial role in regulating metabolic pathways, ensuring that reactions occur in a controlled and efficient manner.
