(We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.Which enzyme activity of the glycogen debranching enzyme is operating during the release of glucose units linked to glycogen branchpoints via a1,6 glycosidic linkage?

These membranous vesicles seal inside out, so that the intermembrane space of themitochondria becomes the lumen of the submitochondrial particle. Explain (or diagram) the process of electrontransfer and oxidative phosphorylation in these particles. Assuming all the substrates for oxidativephosphorylation are present in excess, does ATP synthesis increase or decrease with an increase in the pH ofthe fluid in which the submitochondrial particles are suspended?
