Question #11 of 32: Rotenone is a poison commonly added to insecticides. Insects exposed of rotenone will die because

A.they will no longer be able to produce adequate amounts of ATP.

B. they will no longer be able to perform anaerobic respiration.

C. high levels of fermentation products will build up in their bodies.

D. they will no longer be able to absorb water and will become dehydrated.

Question #12 of 32: Cyanide differs from dinitrophenol in that

A.cyanide inhibits the production of ATP by inhibiting ATP synthase, while dinitrophenol causes mitochondrial membranes to become less permeable to H+ ions.

B. cyanide makes the membrane of mitochondria leaky to H+ ions and prevents a concentration gradient from building up, while dinitrophenol blocks the passage of electrons through electron carriers.

C. cyanide is an electron transport blocker, while dinitrophenol makes the membrane of the mitochondrion leaky to H+ ions.

D. cyanide is highly toxic to human cells, while dinitrophenol is nontoxic.

Question #13 of 32: Which of the following statements about the energy yield of aerobic respiration is false?

A.Less than 50% of the chemical energy available in glucose is converted to ATP energy.

B. Oxidative phosphorylation resulting from 1 glucose molecules yields about 12 ATP molecules.

C. The total yield of ATP molecules per glucose molecules is about 32.

D. Most of the ATP derived during aerobic respiration results from oxidative phosphorylation.

Question #14 of 32: The energy yield from complete aerobic breakdown of a single molecule of glucose.

A.can vary depending on whether NADH passes its electrons to NAD+ or FAD.

B. increases as the supply of oxygen increases.

C. is less than the yield from anaerobic respiration.

D. is always 32 ATP.

Question #15 of 32: Which of the following processes produces the most ATP per molecule of glucose oxidized?

A.alcoholic fermentaion

B. aerobic respiration

C. lactic acid fermentation

D. All produce approximately the same amount of ATP per molecule of glucose.
