What is the role of NAD+ in cellular respiration?to receive electrons from the citric acid cycle and deliver them to the electron transport chainto catalyze the synthesis of ATP from ADPto accumulate in the mitochondrial intermembrane space to facilitate ATP synthesisto serve as a substrate to bind to acetyl-CoA at the beginning of the citric acid cycleNone of the answers are correct.2.How is the energy from the electron transport chain used most directly?to form the bonds of a water moleculeto pump hydrogen ions across the mitochondrial inner membrane into the mitochondrial intermembrane spaceto join ADP with a phosphateto decompose glucose into pyruvateto rotate ATP synthase3.In the process of alcoholic fermentation, what causes the liquid to bubble?oxygencarbon dioxidenitrogenalcoholsugar4.Which molecules transport electrons from the citric acid cycle to the electron transport chain?NADH and FADH2ATP and ADPGTP and GDPoxaloacetate and citric acidNone of the answers are correct.5.What causes the ATP synthase rotor to spin?the passing of electrons through ATP synthasethe movement of protons across the mitochondrial membranethe movement of electrons across the mitochondrial membranethe synthesis of ATP from ADP and a phosphate groupNone of the answers are correct.6.Which process provides the energy needed to pump protons across the mitochondrial membrane during oxidative phosphorylation?the transfer of electrons in redox reactionsthe breakdown of ATP to ADPthe rotation of the ATP synthase rotoroxidation of isocitrateNone of the answers are correct.7.Which biochemical process do aerobic respiration, anaerobic respiration and fermentation all have in common?glycolysiscitric acid cycleoxidative phosphorylationelectron transport chainnon-oxygen molecules as final electron acceptors8.Which process in oxidative phosphorylation releases energy?the transfer of electrons in redox reactionsthe buildup of H+ ions on one side of the mitochondrial membranethe rotation of the ATP synthase rotorthe synthesis of ATP from ADP and a phosphate groupAll answers are correct.9.Which of the following atoms has the highest electronegativity?sulfuroxygenhydrogennitrogencarbon10.Suppose a microorganism invades a cell, causing damage to ATP synthase. How would cellular respiration be affected?Electrons could not be passed down the electron transport chain.ADP could not be joined with a phosphate to form ATP.Hydrogen ions could not be pumped into the mitochondrial intermembrane space.The cell could not release any energy from the glucose molecule.Glucose could not be broken down into pyruvate.11.What is the function of oxidation reactions in the citric acid cycle?to catalyze ATP synthesisto release energy from substrate moleculesto oxidize NAD+ to NADHto break down glucose into pyruvateAll answers are correct.12.Which statement regarding facultative anaerobes is true?They can survive in the presence or absence of oxygen.They require oxygen to survive.They require the absence of oxygen to survive.They cannot metabolize glucose.They require carbon dioxide to survive.
