1. You have given all the enzymes and intermediates in glycolysis. Choose the right enzymes and intermediates and draw the glycolytic pathway. Decorate the diagram by adding ATP, ADP, H", NADH, NAD', P, and H20 where necessary. All the steps are reversible except 1, 3 and 10; draw appropriate arrow. First arrange the reactants in the correct order. Reactants/intermediates: 3-phosphoglycerate glucose Phosphoenolpyruvate dihydroxyacetone phosphate Pyruvate glucose 6-phosphate 1,3-bisphosphoglycerate fructose 6-phosophate 2-phosphoglycerate glyceraldehyde 3-phosphate fructose 1,6-bisphosphate Enzymes: Phosphoglucoisomerase phosphoglycerate kinase phosphoglycerate...
