3. Oxidative phosphorylation (50 pts) A) In his studies of alcoholic fermentation by yeast, Louis Pasteur noted that the sudden addition of oxygen (O,) to a previously anaerobic culture of fermenting grape juice resulted in a dramatic decrease in the rate of glucose consumption. This "Pasteur effect can be counteracted by the addition of 2.4-dinitrophenol (DNP), an uncoupler of oxidative phosphorylation. 0) Why would the yeast cells consume less glucose in the presence of oxygen? (ii) How...

Which of the following statements about oxidative phosphorylation is true? a. Oxidative phosphorylation involves the activities of the electron transport chain and the ATP synthesizing machinery. b. The oxidation of NADH is the only way to form ATP. c. ATP is synthesized using the energy that is released when electrons and hydrogen are excreted outside of the cell. d. ATP synthesis occurs during oxidative phosphorylation directly by the reduction of electron carrier proteins in the cytoplasmic membrane.

33) Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? A) Sodium and glucose bind to the same site on the cotransporter. B) Transport of glucose against its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient. C) Sodium ions can be transported whether or not glucose is present outside the cell, but glucose transport requires cotransport of sodium ions. D)...
