    Study Notes

    Enzymes in Bioluminescent Assays

    • Bioluminescent assays utilize luciferases for the detection of various molecules.

    Storage Form of Glucose in Animals

    • Glycogen is the primary storage form of glucose in animals, allowing energy reserve and release as needed.

    Direction of DNA Replication

    • DNA replication occurs in a 5' to 3' direction, where nucleotides are added to the growing strand.

    RNA Carrying Genetic Information

    • Messenger RNA (mRNA) carries genetic information from the nucleus to ribosomes for protein synthesis.

    Type of Radiation

    • Electromagnetic radiation consists of electric and magnetic fields propagating through space and time.

    Molecules Absorbing UV and Visible Light

    • Chromophores absorb ultraviolet (UV) and visible (Vis) light when their energy aligns with the necessary electron promotion energy levels.

    Enzyme Class for Oxidation Reactions

    • Dehydrogenases are the enzyme class responsible for oxidation reactions involving NAD+ as a cofactor.

    Catalytic Region of Enzymes

    • The active site is the main catalytic region of enzymes, providing specificity and reducing the activation energy of the transition state.

    Enzyme Cleaving Peptide Bonds

    • Proteases, also known as peptidases, are enzymes that cleave peptide bonds in proteins.

    Detection Method Using Enzymes in Biosensors

    • Electrochemical biosensors leverage enzymes to produce measurable electrical signals, essential for accurate detection.

    Enzyme for Generating Fluorescent Signals

    • Alkaline phosphatase is commonly used in assays like ELISAs to generate fluorescent signals.

    Enzyme Involved in Carboxylation Reactions

    • Carboxylases are the type of enzymes that catalyze carboxylation reactions, adding carbon dioxide to substrates.
