Solved by a verified expert:Most adult humans consume about 2,000 Calories of food energy each day. What might happen to the energy from this food?Select ALL that apply. It could be used in the synthesis of fat or other body tissues. It could be destroyed by the digestion process. It could be used to generate movement, allowing you to climb a mountain or do other activities. It could be transformed into heat and released from your body. It could be excreted as undigested waste in feces, still in its original chemical form.1.The synthesis of ATP in the mitochondria occurs by:A. Transport of electrons to ATP synthase by coenzyme Q.B. An excess proton concentration across a membrane.C. Proton driven conformational changes in ATP synthase.D. Direct coupling to NADH reduction.Question 1Select one answer.10 pointsWhich statement best characterizes the role of enzymes in glycolysis? Several steps do not require enzymes Several steps are catalyzed by a single multifunctional enzyme One multifunctional enzyme catalyzes the whole pathway Each step is catalyzed by a separate enzymeQuestion 2Select one answer.10 pointsThe flow of carbon through glycolysis can be described as: Oxidation of a six carbon sugar. Oxidation of a six carbon sugar, followed by cleavage into two three carbon molecules. Cleavage of a six carbon sugar into two three carbon molecules, followed by their oxidation. Conversion of glucose into carbon dioxide.Question 3Select one answer.10 pointsGlycolysis does not require O2 to generate energy requires O2 to generate energy is inhibited by O2 rate is increased in the presence of O2Question 4Select one answer.10 pointsThe phosphorylation of glucose to glucose 6-phosphate (G-6-P) Occurs without a catalyst. Is so favorable that the source of phosphate is not important. Is so favorable that it can be used to synthesize ATP. Requires energy from ATP to occur.Question 5Select one answer.10 pointsGlucose is prevented from leaving the cell once it enters because: It is converted to glucose-6-P, which cannot cross the membrane. It is converted to glucose-6-P, which cannot exit through the glucose transporter. It is used immediately for glycolysis.Question 6Select one answer.10 pointsThe conversion of F-1,6-P to two three carbon sugars by the enzyme aldolase has a standard energy change of +25 kJ/mol. This reaction is sponaneous in glycolysis with a Gibbs energy of ~0 because: One of the products of aldoase is phosphorylated by ATP. A subsequent reaction in glycolysis is highly favorable. Aldolase lowers the Gibbs energy. NADH is used as an energy source.Question 7Select one answer.10 pointsThe energy released by glucose oxidation is captured on _____ and _____. ATP, NADH NADH, proton gradient NAD+,ADP ATP, FADH2Question 8Select one answer.10 pointsAlcohol dehydrogenase in yeast serves the same role as lactate dehydrogenase in mammals. This role is: To remove excess pyruvate. To regenerate NAD+from electron transport. To regenerate NAD+for glycolysis. To reduce the amount of oxygen needed for growth.Question 9Most adult humans consume about 2,000 Calories of food energy each day. What might happen to the energy from this food?Select ALL that apply. It could be used in the synthesis of fat or other body tissues. It could be destroyed by the digestion process. It could be used to generate movement, allowing you to climb a mountain or do other activities. It could be transformed into heat and released from your body. It could be excreted as undigested waste in feces, still in its original chemical form.Question 10Which of the following options best describes how energy flows through a consumer? ATP ? anabolic reactions ? organic molecules ? catabolic reactions ? anabolic reactions and other cellular work organic molecules ? catabolic reactions ? ATP ? anabolic reactions and other cellular work organic molecules ? anabolic reactions ? ATP ? catabolic reactions inorganic molecules ? ATP ? organic molecules ? anabolic reactions and other cellular work
