Which of the following biomolecules is common to respiration-mediated breakdown of fats, carbohydrates and proteins

Options

A. Glucose-6-phosphate
B. Fructose 1,6-bisphosphate
C. Pyruvic acid
D. Acetyl Co-A

Answer

D

Explanation

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 is then converted into fructose-6-phosphaste adn purther to fructose 1-6-bisphosphate. Pyruvic acid is the end product of glycolysis.
