Concept explainers
(a)
Interpretation: To identify the step of the citric acid cycle in that ATP-precursor-molecule generated is equivalent to 2.5 units of ATP.
Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and
NADH is the reduced form of nicotinamide adenine dinucleotide. It is employed as an oxidizing agent in various reactions like oxidation of secondary alcohol into a
(b)
Interpretation: To identify the step of the citric acid cycle in that ATP-precursor-molecule generated is equivalent to 1.5 units of ATP.
Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and
FADH2 is the reduced form of flavin adenine dinucleotide. The main function of flavin adenine dinucleotide is to act as an oxidizing agent and used by the cell in oxidation reactions like oxidation of fatty acid.
(c)
Interpretation: To identify the step of the citric acid cycle in that ATP-precursor-molecule generated is equivalent to 1.0 units of ATP.
Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and

EBK GENERAL, ORGANIC, AND BIOLOGICAL CH
- Which of the following statements concerning ATP synthesis is NOT true? a. The open conformation of the ATP synthase is for releasing ATP. b. The gamma subunit in the stalk responds to the flow of H+ and rotates the assembly counterclockwise and thus change the conformations of the active site to synthesize ATP. c. The tight conformation of the ATP synthase is for converting ADP and phosphate to ATP. d. The loose conformation of the ATP synthase is for binding ADP and phosphate. e. Ten protons are required to catalyze the rotation of the subunits so that one ATP is synthesized. Clear my choicearrow_forwardYou are testing the effects of different molecules on respiration using isolated liver cells that are growing on glucose. For each of the compounds listed below, indicate whether the compound will increase or decrease respiration (measured by monitoring oxygen consumption), and provide reasoning for your answer in two sentences at most. Consider only the early time after the compound begins to exert its effects. a. An inhibitor of the FoF1 ATPase b. A proton channel that enables protons to cross the inner mitochondrial membrane by facilitated diffusion c. An inhibitor of NADH dehydrogenase (complex I of the electron transport chain)arrow_forwardWhen ATP is hydrolyzed to produce ADP and phosphate the chemical reaction is Select one: a. Endergonic b. Neither releases nor requires input of energy c. Exergonicarrow_forward
- When ATP synthase converts ADP and Inorganic phosphate into ATP what type of reaction is this.arrow_forward(b) Metabolic state of cells and organism can be associated with inmplication of ATP and NADH. Explain this relationship.arrow_forwardWhich of the following statement about ATP formation in Glycolysis is True? a. Four ATP molecules are used in the Glycolysis of one molecule of Glucose b. Three ATP molecules are formed in the Glycolysis of one molecule of Glucose c. Two ATP molecules are used in the Glycolysis of one molecule of Glucose d. Two ATP molecules are formed in the Glycolysis of one molecule of Glucosearrow_forward
- Given 60 glucose molecules available in a muscle fiber to undergo aerobic respiration, how many H+ protons can be pumped by transport proteins if the glycolytic NADH followed the Glycerol Phosphate Shuttle? a. 120 H+ protons b. 240 H+ protons c. 360 H+ protons d. 720 H+ protonsarrow_forwardExplain the “coupling” effect of ATP on catabolism and anabolism (please use the image for reference. thanbk you)arrow_forwardUse the first step in glycolysis to explain how ATP can power reactions that would otherwise not take place (Explain with calculations)arrow_forward
- Briefly explain how ATP synthase produces ATP by describing how the three conformations work (loose, tight, open)arrow_forwardUnder conditions where cellular ATP levels are high the rate of electron transport in mitochondria slows down. This is referred to as “respiratory control” What is the mechanism behind respiratory control? A. A high pH gradient slows proton pumping, which in turn slows electron transport. B. Glucose binds to the ATP synthase complex slowing the rate of diffusion of protons across the membrane. C. Molecules of UQ within the membrane change shape, which slows their rate of diffusion. D. ATP binds to NADH dehydrogenase complex (Complex 1) slowing the rate of NADH oxidation.arrow_forwardWhat drives the rotation of the F1 head (rotor) of ATP synthase? a. proton movement from intermembrane space to the matrix b. proton movement from the matrix to the intermembrane space c. ATP hydrolysis d. ATP condensation e. proton movement from the cytoplasm to the intermembrane spacearrow_forward
