    Study Notes

    Phosphorylation

    • Refers to the addition of a phosphate group to a molecule, typically involving ADP and inorganic phosphate (P).
    • The process generates ATP and produces water as a byproduct.

    ATP Production

    • Word equation: ADP + P + Energy = ATP + H₂O.
    • Represents how energy is stored in the form of ATP, a key energy currency in cells.

    Advantages of ATP

    • ATP is a reusable energy source, allowing cells to regenerate it multiple times for various cellular processes.

    NADH

    • High-energy molecule that plays a critical role in transferring high energy electrons.
    • Essential for ATP production during the electron transport chain.

    Full Name of NADH

    • Nicotinamide adenine dinucleotide.

    NADPH

    • High-energy molecule used for transferring electrons and a H+ ion, particularly in plants.
    • Vital for the Calvin Cycle in the process of glucose synthesis.

    Full Name of NADPH

    • Nicotinamide adenine dinucleotide phosphate.

    NADH Production

    • Word equation: NAD⁺ + H⁺ + 2e⁻ = NADH.
    • Describes the reduction of NAD⁺ to NADH, essential for energy metabolism.

    NADPH Production

    • Word equation: NADP⁺ + H⁺ + 2e⁻ = NADPH.
    • Highlights the conversion of NADP⁺ to NADPH, important in photosynthetic processes.
