Additional information: ATP production by the ETC and ATP Synthase per glucose varies somewhat depending on the energy required to move NADH into the mitochondria and other energy uses for the hydrogen-ion gradient. Additional questions: 1.) How many ATP's are generally yielded by oxidative phosphorylation from the catabolism of one glucose? 2.) Summarize the total ATP's obtained from a single molecule of glucose, from start to finish?

Bioenergetics: Answer the following questions regarding bioenergetics/ oxidative phosphorylation:
Given the following reactions and AGs for each reaction, answer the two questions that follow; be sure
to give complete answer including proper units and sign(s) wherever necessary:
Reaction #1 (AG = -2.3 kcal/mol): A+ B2 C+D
Reaction #2 (AG = +5.3 kcal/mol): C+ K 2R
Reaction #3 (AG = -4.5 kcal/mol): R 2 Y+Z
7. Calculate AG for overall reaction: AR>Z Free Energy Change Reactions #1-3 =
8. Which direction is this overall process (#1-3) predicted to go (circle one)? forward OR backward
Efficiency of ATP Production in Muscle: The transformation of glucose to lactate in myocytes releases only about 7% of the free energy released when glucose is completely oxidized to CO2 and H2O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose? Explain.
