NEET2013BotanyRespiration in PlantsActual
Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?
Options
- AGlucose-6-phosphate
- BFructose 1, 6-bisphosphate
- CPyruvic acid
- DAcetyl Co-A
Correct answer
D. Acetyl Co-A
Step-by-step solution
Acetyl Co-A is common to respiration mediated breakdown of fats, carbohydrates and proteins. Glucose and fructose are phosphorylated to give rise to glucose6-phosphate by the activity of the enzyme hexakinase. Glucose-6-phosphate then converts into fructose 6 phosphate and further to fructose 1-6-bisphosphate. Pyruvic acid is the end product of glycolysis.
