    Study Notes

    Fermentation Process

    • The final product of the fermentation process is ethanol and carbon dioxide.

    Initial Stage of Fermentation

    • The first stage of fermentation is the breakdown of carbohydrates into glucose.

    Carbohydrates

    • Carbohydrates are best conceived as a source of energy for the body.
    • The empirical formula for carbohydrates is CH₂O.
    • Carbohydrates can be categorized into two groups: simple (sugars) and complex (starches and fibers).
    • Complex carbohydrates can be hydrolyzed to simpler compounds.

    Glucose

    • Glucose is a type of simple carbohydrate, classified as a monosaccharide.
    • Glucose is synthesized in plants through the process of photosynthesis.

    Anaerobic Respiration

    • One of the stages of fermentation, anaerobic respiration, does not use oxygen.

    Initiation of Fermentation

    • The compound that initiates the fermentation process is zymase, an enzyme present in yeast.
