During glycolysis, what is the logic behind phosphorylation of C1 and C6 of fructose?

a. Phosphorylation ensures that products of C-C bond cleavage are interconvertible

b. Phosphorylation ensures that intermediates remain in the cell

c. More than one of these choices

d. None of the choices listed

e. Phosphorylation ensures that two products are funneled into single pathway

Solution

a. Phosphorylation ensures that products of C-C bond cleavage are interconvertible

Phosphorylation of fructose is 3rd step in the glycolysis. This step ensures the interconversion of products resulting from C-C cleavage. Phosphorylation of glucose ensure that the intermediates remain in the cell.
