    Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?

    A)  Glucose-6-phosphate

    B)  Fructose 1, 6-bisphosphate

    C)  Pyruvic acid

    D)  Acetyl Co-A

    Correct Answer: D

    Solution :

    Acetyl Co-A is common to respiration mediated breakdown of fats, carbohydrates and proteins. Glucose and fructose are phosphorylated to give rise to glucose-6-phosphate by the activity of the enzyme hexokinase. Glucose-6-phosphate then converts into fructose 6 phosphate and further to fructose 1-6-bisphosphate. Pyruvic acid is the end product of glycolysis.
