    Study Notes

    Energy and ATP

    • Exergonic reactions are a type of reaction that releases energy from the system.

    DNA Replication

    • The main function of DNA polymerase is to synthesize new DNA strands by adding nucleotides to a template.

    ATP Structure

    • ATP (Adenosine Triphosphate) is composed of adenine, ribose, and three phosphate groups.

    ATP Hydrolysis

    • Hydrolysis of ATP with water releases 30.5 kJ of energy per mole of ATP.

    Energy Production

    • The process by which photosynthesis and/or respiration provide the energy required to synthesize ATP is called energy coupling.

    ATP Function

    • The main function of ATP hydrolysis in the cell is to provide energy for various cellular processes.

    Photosynthesis

    • Photoautotrophs are organisms that use light energy, carbon, and water to produce organic molecules through photosynthesis.

    Electron Carriers

    • The main function of NAD+/NADH in cellular respiration is to facilitate electron transport and generate ATP.

    Aerobic Respiration

    • The products of aerobic respiration of glucose are carbon dioxide, water, and ATP.

    Redox Reactions

    • The main function of oxidation and reduction in living systems is to facilitate energy transfer and storage.
