    Study Notes

    Enzymes and Their Functions

    • Enzymes act as biological catalysts, speeding up biochemical reactions by lowering activation energy.
    • They play a crucial role in metabolic pathways, facilitating digestion, energy production, and biosynthesis.

    Conjugated Enzymes

    • Conjugated enzymes require specific non-protein molecules known as cofactors or coenzymes for their activity.
    • Cofactors can include metal ions (e.g., zinc, magnesium) while coenzymes are often derived from vitamins (e.g., NAD, FAD).

    Enzyme Nomenclature

    • Enzymes that retain their original names without indicating the associated reaction are typically known as 'systematic' or 'recommended' names.
    • This type often does not reflect the specific substrate or type of chemical reaction catalyzed.

    Enzyme Descriptions and Definitions

    • Accurate matching of terms to definitions is essential in understanding enzyme functions, mechanisms, and classifications.
    • Familiarity with nomenclature helps to understand enzymatic reactions and their biological significance.
