    Study Notes

    Cellular Respiration Overview

    • Cellular respiration is a biochemical process that breaks down glucose and other food molecules in the presence of oxygen to release energy.
    • It occurs primarily in the mitochondria of eukaryotic cells.

    Key Components

    • Mitochondria are known as the powerhouses of the cell, where glucose is converted to ATP (adenosine triphosphate).
    • Glucose is a simple sugar that acts as an energy reservoir, derived from photosynthesis.

    Reactants and Products

    • Reactants of Cellular Respiration: Glucose and Oxygen (C6H12O6 + 6O2).
    • Products of Cellular Respiration: Carbon Dioxide, Water, and Energy (6CO2 + 6H2O + energy).

    Chemical Equations

    • The equation for cellular respiration is represented as:
      C6H12O6 + 6O2 → 6CO2 + 6H2O + energy.
    • The reverse process, photosynthesis, is represented as:
      6CO2 + 6H2O + energy → C6H12O6 + 6O2.

    Relationship with Photosynthesis

    • Photosynthesis and cellular respiration are opposite processes. Photosynthesis captures energy to form glucose, while cellular respiration releases energy by breaking it down.

    Energy Currency

    • ATP is the direct product of cellular respiration and serves as the primary energy currency for cellular activities.

    Gases Involved

    • Carbon Dioxide is released as a waste product of cellular respiration and is utilized in photosynthesis.
    • Oxygen is produced as a byproduct of photosynthesis and is essential for cellular respiration.
