a. It allows for increased rate of glycolysis. b. It allows for increased rate of the citric acid cycle. It increases the surface for oxidative phosphoryation. c. d. It increases the surface for phosphorylation. e. It allows the liver cell to have fewer mitochondria. Use the following to answer the following questions. Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes. However, the fragments will reseal "inside out." These little vesicles that result can still transfer electrons from NADH to oxygen and synthesize ATP. If the membranes are agitated still further however, the ability to synthesize ATP is lost. It should be possible to reconstitute the abilities of the vesicles if which of the following is added? ____ 124. a. cytochromes NADH b. c. a second membrane surface d. more electrons e. intact ATP synthase Figure 9.3 The accompanying figure shows the electron transport chain. Which of the following is the ____ 125. combination of substances that is initially added to the chain? a. oxygen, carbon dioxide, and water b. NAD, FAD, and electrons c. NADH, , and protons d. NADH, , and electrons Oxygen and electrons e. Which of the following most accurately describes what is happening along this chain? ____ 126. a. Chemiosmosis is coupled with electron transfer. b. Each electron carrier alternates between being reduced and being oxidized. c. ATP is generated at each step. d. Energy of the electrons increases at each step. e. Molecules in the chain give up some of their potential energy. The parts of the figure labeled with Roman numerals symbolize what concept? ____ 127. a. different inner mitochondrial membranes different mitochondria functioning together b. c. molecules with different attached metal ions d. carbohydrate framework holding the molecules in place e. multimeric groups of proteins in 4 complexes What happens at the end of the chain? ____ 128. a. The 2 original electrons combine with NAD.
