2. What is the significance of the isomerization of glucose 6-phosphate to fructose 6-phosphate for the progression of glycolysis? (A) As functional groups, ketones are more reactive than aldehydes. (B) Cleavage of glucose 1,6-bisphosphate will not yield dihydroxy acetone phosphate and glyceraldehyde 3-phosphate. (C) The carbonyl group at carbon-2 (C-2) in fructose facilitates the cleavage of the bond between C-3 and C-4. (D) Phosphorylation of glucose 6-phosphate to glucose 1,6-bisphosphate is irreversible.
