Glucose-6-phosphate

B

Fructose-1,6 biphosphate

C

Pyruvic acid

D

Acetyl Co-A

Text Solution

Verified by Experts

The correct Answer is:
D
(d)Carbohydrates,fats and proteins,all can be used as a substrate in cellular respiration.All of them first get converted to acetyl Co-A to enter into krebs' cycle of aerobic cellular respiration.Thus,it is the common factor of respiration entering krebs' cycle after breakdown of carbohydrates,fats and proteins.
