Question 5 Which of the following subunits of ATP synthase is correctly described? a: site of ATP synthesis y: protons are transferred to this subunit, determines the number of protons transferred per ATP formed a: contains two half channels for transferring protons across the membrane
Question 23 2 pts As it turns out, arsenic is a competitive inhibitor of pyruvate dehydrogenase. Suppose you add arsenic to human muscle tissue in a laboratory. What results would you expect to observe? I. Decreased ability of the tissue to relax after contraction II. Increased concentration of ADP in the mitochondrial matrix III. Increased concentration of lactic acid in the cytosol IV. Increased concentration of NADH and FADH2 in the mitochondrial matrix I, II, and IV II, III, IV I and II I and IV I, II, and III
QUESTION 52 An organism is discovered that thrives in both the presence and absence of oxygen in the air. Curiously, the consumption of sugar increases as oxygen is removed from the organism's environment, even though the organism does not gain much weight. This organism O a. is photosynthetic O b. is a normal member of the animal kingdom O c. must utilize a molecule other than oxygen to accept electrons from the electron transport chain O d. only performs fermentation to make ATP
Question 8 Which of the following is NOT a characteristic of aerobic metabolism? O A. Carbon dioxide is produced in the matrix of the mitochondria. O B. Oxygen is reduced to water by the electron transport chain. C. Lactic acid is produced in the cytoplasm. OD. ATP synthase requires a pH gradient O E. The electron transport chain functions as hydrogen ion pumps. mennes Mausantara **** Eminem
Question 29 Sponges (Porifera) All of the above pump water through their sponge material with the movement of collar cells Have larvae that swim using cilia Extract oxygen from the sea water Are assemblies of cells that work together cooperatively as one organism
Question 9 - Under anaerobic conditions in the muscle, lactate dehydrogenase catalyzes the reaction converting pyruvate to lactate. What is the metabolic reason for this fermentation reaction? It is necessary to reduce pyruvate before it can be converted to acetyl-CoA and enter the citric acid cycle in muscle. NAD* must be replenished for glycolysis to continue. The reaction creates NADH which can produce additional energy in the electron transport chain. O Lactate is more oxidized than pyruvate.

Question 18 In a photosynthetic cell undergoing cell expansion and growth involving active synthesis of multiple proteins, which of the following would you expect to be false? O photo-respiratory activity would increase O Nucleolar activity would be elevated O All of the possible answers are true O Mitochondrial activity will increase O Non-Cyclic electron transport would be greater than cyclic electron transport
Question 1: The amount of energy effectively stored in each ATP (the actual energy of ATP hydolysis) will depend on the concentrations of ATP, ADP, and Pi, according to equations discussed in class and in the book. If the ATP synthase is operating at close to equilibrium (as might be the case if ATP is being used slowly), we can compute the maximum possible energy of ATP hydrolysis by assuming balance between the energy provided by the proton gradient and the energy used to make the ATP. (Since we care about the magnitude of the energy it’s convenient to talk in terms of absolute values; the maximum possible ATP hydrolysis energy is then the most negative value possible.) Using what you know about the mechanism of the ATP synthase, and assuming that the membrane gradient consists of a Δψ of -.15V and a ΔpH of 1 unit (alkaline inside), compute the maximum possible ATP-hydrolysis energies for synthases with: a.) 8 c-subunits b.) 13 c-subunits
