    Study Notes

    Energy Flow and Cellular Processes

    • The primary function of cellular respiration is to generate energy for the cell through the breakdown of glucose and other organic molecules.

    Photosynthesis and Plant Cells

    • Photosynthesis takes place in the chloroplasts of a plant cell.

    Electron Transfer and Catabolic Pathways

    • Electron transfer plays a crucial role in catabolic pathways, facilitating the transfer of energy from high-energy molecules to lower-energy molecules, ultimately generating ATP.

    Energy Flow in Ecosystems

    • The ultimate fate of energy that flows into an ecosystem as sunlight is to be converted into ATP, which is then utilized by organisms to perform cellular work.

    Energy Source for Animals

    • The source of energy for animals to perform cellular work is the food they consume, which is broken down through cellular respiration to generate ATP.
