1. Which of the following types of reactions would decrease the entropy within a cell? a. Catabolism 2. Enzymes are potent catalysts because they a. Lower the activation energy for the reactions they catalyze 3. The enzyme malate dehydrogenase catalyzes the conversion of oxaloacetate to a molecule containing five carbon atoms and the loss of CO2 4. During oxidative phosphorylation, the proton motive force that is generated by electron transport is most directly used to: a. Oxidize NADH to NAD+ 5. All of the events occur in the light reactions of photosynthesis a. Light is absorbed and funneled to reaction center chlorophyll a b. Carbon dioxide is incorporated in to PGA c. ADP is phosphorylated to yield AT d. NADP+ is reduced to NADPH 6. Oxygen is NOT produced in the light reactions of photosynthesis 7. When 10,000 molecules of ATP are hydrolyzed to ADP and Pi in a test tube, about twice as much heat is liberated as when a cell hydrolyzes the same amount of AT. Which of the following is the best explanation for this observation
