    Study Notes

    Cellular Respiration Overview

    • Begins with glucose, the primary energy source for cellular processes.
    • Involves multiple stages, including glycolysis, the citric acid cycle, and the electron transport chain.

    Glycolysis

    • Occurs in the cytoplasm of the cell.
    • Breaks down glucose to produce 2 pyruvic acids.
    • Results in a net gain of 2 ATP molecules.
    • Can function under both aerobic and anaerobic conditions.

    Anaerobic Processes

    • An example is fermentation, which occurs when oxygen is not available.
    • Fermentation converts pyruvic acid into lactic acid, resulting from anaerobic respiration.

    Aerobic Respiration

    • Begins with the citric acid cycle, which utilizes acetyl CoA.
    • Takes place in the mitochondria, the powerhouse of the cell.
    • Produces a net yield of 2 ATP, along with 6 NADH and 2 FADH2 molecules.
    • Releases 2 CO2 molecules as waste products.

    Electron Transport Chain

    • The products of the citric acid cycle are utilized here.
    • Situated in the mitochondria and responsible for generating a significant amount of ATP, approximately 34 ATP molecules.
