Step 6 of Glycolysis - Answer-- glyceraldehyde-3-phosphate dehydrogenase uses NAD+ and Pi to oxidize and phosphorylate C1 of glyceraldhyde-3-phosphate to 1,3-bisphosphoglycerate - ATP is not used - NAD+ is reduced to NADH - positive deltaG - active site Cys residue is required Step 7 of Glycolysis - Answer-- phosphoglycerate kinase removes a phosphate group from C1 of 1,3-bisphosphoglycerate and adds it to ADP to make 3-phosphoglycerate and ATP - negative deltaG - helps pull step 6 forward - carboxyl group is on C1 Step 8 of Glycolysis - Answer-- phosphoglycerate mutase moves a phosphate group on C3 of 3-phosphoglycerate to C2 to form 2-phosphoglycerate - active site with phosphorylated His residue is required - involves a bisphosphate intermediate - freely reversible
