    Question: What is the end product of anaerobic respiration?

    Options:

    Pyruvic acid and energy
    Alcohol, carbon dioxide and energy
    Carbon dioxide and water
    Carbon dioxide, water and energy

    The correct answer is Alcohol, carbon dioxide and energy.
    Concept-
    -An important feature of all living cells is respiration which is related to the liberation of metabolic energy as ATP.
    -Respiration is an amphibolic and exergonic cellular process.
    -Respiration is of two types.
    -Aerobic respiration- with the use of oxygen. Eg plants
    -The equation of Aerobic Respiration
    -Glucose + Oxygen → Carbon dioxide + Water + Energy
    -Anaerobic respiration- without the use of oxygen. Eg yeast
    -The equation of Anaerobic Respiration
    -Glucose → Alcohol + Carbon dioxide + Energy
    -2 molecules of ATP are obtained by the anaerobic respiration of one molecule of glucose.
    -Respiration is a glucose degradation mechanism with the aid of molecular oxygen to generate ATP.
    -It requires both glycolysis and phosphorylation.
    -Glycolysis is the first step of glucose degradation that occurs in the absence of oxygen and transforms one glucose molecule into two pyruvate molecules.
    -During this cycle, 4 ATP molecules are generated and 2 ATP molecules are consumed.
