    Study Notes

    Cellular Respiration

    • Cellular respiration is the process by which cells break down glucose and other food molecules to generate ATP, the primary energy currency of the cell.

    Stages of Cellular Respiration

    • There are four main stages:
      • Glycolysis: Glucose is broken down into pyruvate, producing a small amount of ATP and NADH. This occurs in the cytoplasm.
      • Pyruvate Oxidation: Pyruvate is converted to acetyl-CoA, generating more NADH. This occurs in the mitochondrial matrix.
      • Citric Acid Cycle (Krebs Cycle): Acetyl-CoA is broken down, releasing CO2 and generating more ATP, NADH, and FADH2. This occurs in the mitochondrial matrix.
      • Electron Transport Chain: The high-energy electrons carried by NADH and FADH2 are passed along a series of protein complexes, creating a proton gradient across the inner mitochondrial membrane. This gradient is used to generate a large amount of ATP through oxidative phosphorylation. This process occurs in the inner mitochondrial membrane.

    ATP Production

    • The breakdown of one glucose molecule can yield up to 38 ATP molecules.
    • Most of the ATP is generated through oxidative phosphorylation in the electron transport chain.

    Regulation of Cell Respiration

    • The rate of cellular respiration is tightly regulated to meet the energy needs of the cell.
    • Factors that can influence the rate of respiration include:
      • The availability of glucose and oxygen
      • The concentration of ATP and ADP
      • Hormonal signals
