- i have a question from Lehninger, bichemistry, 13-16 and i know that there is already a copy paste answer from the book for the question on bartleby, howerver I do not understand it and need explained further, as the answere in the book does not help me at all. In the glycolytic pathway, a six-carbon sugar (fructose 1,6-bisphosphate) is cleaved to form two three-carbon sugars, which undergo further metabolism. In this pathway, an isomerization of glucose 6-phosphate to fructose 6-phosphate (as shown in the diagram) occurs two steps before the cleavage reaction. The intervening step is phosphorylation of fructose 6-phosphat to fructose 1,6-bisphosphate What does the isomerization step accomplicsh from a chemical perspective? Consider what might happen if the C-C bond cleavage were to proceed without the preceding isomerization.Question 21 Which two of following confribute to the large negative free energy change upon hydralynis of "high energy compounds?
