Like many fruits, apples contain not only fructose and glucose, but also sucrose, a dimerof fructose and glucose. Synthesizing sucrose is endergonic and so not spontaneous. Onerole of ATP is to facilitate reactions that would not occur spontaneously. The threephosphate groups are electron rich and tend to repel each other. Therefore, ATP is a bitlike a compressed spring, ready to kick off one phosphate group releasing energy.Consider: Fructose + glucose --> Sucrose delta G= 6.4 kcal/mol ATP --> ADP + Pi delta G= -7.3 kcal/mol a. Draw a simple energy diagram (including the relative energy of the reactants andproducts) that shows why the sucrose synthesis reaction doesn’t occur spontaneously. b. How could having these two reactions occur at the same time help with sucroseproduction? c. Draw the energy diagram that shows all the reactants and products for the combinedreactions. d. What is delta G for the combined reactions? e. Name a few of the biological processes in the body that…

Using good organization skills, check over your map of the steps in photosynthesis. Your flowchart should include these concepts and details: • location in the organelle the reactions occur, • the type of biochemical reactions or cellular transport, • the substrates and products for the overall process, • vocabulary and terminology that allow you to demonstrate your understanding. Ask yourself these big questions as a way to monitor and improve your work: • Is the information I have presented a complete representation of my learning? • Is the information I have presented correct? • Have I fulfilled the requirements of the task? • Are the steps I describe organized in the correct order?
