1. Diagram and describe the mechanism of the reaction catalyzed by the enzyme Transaldolase, including structures of major intermediates, substrates and products.
2. Write out the linear (oxidative) portion of the Pentose Phosphate Pathway, giving names and structures of substrates and reactants, and the name of each enzyme. Summarize in words what happens at each step. What two products of the linear portion of the Pentose Phosphate Pathway have essential roles in anabolic metabolism? What are these roles?
