16. ChcmicaI Logic In the glycolytic pathway, a six-carbon sugar (tructose 1,6-bisphosphate) is cleaved to form two three-carbon sugars, which undergo further metabolism (see Fig. 14-6). in this pathway, an isomerization of glucose 6- phosphate to fructose 6-phosphate (shown below) occurs two steps before the cleavage reaction (the intervening step is phosphorylation of fructose 6-phosphaie to fructose 1,6-bisphosphale (p. 539)).
What does the isomcnzation step accomplish from a chemical perspective? (Hint: Consider what might happen if the C—C bond cleavage were to proceed without the preceding isomerization.)
