Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?
Glucose-6-phosphate
Fructose 1, 6-biphosphate
Pyruvic acid
Pyruvic acid
D.
Pyruvic acid
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 to the enzyme hexokinase.
Glucose -6- phosphate then converts into fructose 6 phosphate and further to fructose 1-6- biphosphate. Pyruvic acid is the end product of glycolysis.
