Options:
A) Glucose-6-phosphate
B) Fructose 1, 6-bisphosphate
C) Pyruvic acid
D) Acetyl Co-A
Show Answer
Answer:
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.
