Concept explainers
(a)
Interpretation:
The energy carrying product of oxidative phosphorylation should be identified.
Concept Introduction:
Oxidative phosphorylation: The production of
Adenosine triphosphate ATP: The main job of ATP is to store energy and release it when cell is in need of energy.
Electron transport chain
(b)
Interpretation:
The product other than the energy carrying product released from oxidative phosphorylation should be identified.
Concept Introduction:
Oxidative phosphorylation: The production of
Electron transport chain

- a) What happens during the two phases of glycolysis? Write the reaction steps of glycolysis showing their the enzymes that catalyze the reactions. (Draw only the structure of the first and last product) b) How many net moles of ATP can be synthesized from each mol of glucose? c) The overall equation for glycolysis?arrow_forwardDCCD (diocyclohexylcarbodiimide) inhibits oxidative phosphorylation when the substrate is mitochondrial NADH. DCCD is a drug that binds to ATP synthase and blocks proton transport through the ion channel. a) Explain what the consequences of DCCD on cellular energy production are. b) Suggest at least one other cellular effect of DCCD and explain this effect.arrow_forwardIndicate whether the following statements are true or false:- a) The pentose phosphate pathway of glucose oxidation can lead to the release of energy. b) NAD + is a coenzyme of transketolase.arrow_forward
- The citric acid cycle contains four 4-carbon dicarboxylic acids. (a) Name them.(b) Arrange them in order from least oxidized to mostoxidized.arrow_forward..a) Draw all of the reactions that occur in the aerobic metabolism of glucose that hydrolyze a thiolester bond. In your answer, include complete structural formulae as well as the names of any cofactors, enzymes, reactants and products. b) Explain why the free energy changes that characterize these reactions are so exergonic. Include a figure in your answer. ( c) If you were to completely catabolize 3 molecules of glucose under aerobic conditions, what would the ATP yield be as a result of the reactions that you've drawn above?arrow_forward(a)What are the two superfamilies of proteins in which amylase is categorized? (b)To which superfamily of proteins does active site of the amylase belong?arrow_forward
- Determine whether the following statements are true or false:- a) The pentose phosphate pathway of glucose conversion is a supplier of NADPH (H +) for reductive syntheses. b) An overdose of insulin causes hypoglycemia in a patient with diabetes mellitus. c) Fructose-6-phosphate is an allosteric regulator of glycolysis.arrow_forwardIn oxidative phosphorylation, what is oxidized and what is phosphorylated?arrow_forwardthe reaction catalyzed by glyceradehyde 3-phosphate dehydrigenase is based on NAD+ and a active site cysteine. Also another phosphate group is added. what is the reason for that? a) because one ATP is consumed b) an inorganic phosphate is activated for ATP synthesis C) NADH can be recycld and than converted back to NAD+ for glycolysis d) because one ATP is generatedarrow_forward
- Consider the steps of the krebs cycle and electron carrier chain and answer: a) How many ATPs are produced from 10 Pyruvato molecules? b) How many ATPs are produced from 12 Acetyl CoA molecules?arrow_forward(a) Convert the ball-and-stick model of B, one of the eight synthetic intermediates in the citric acid cycle, to a structural formula, and name the compound. (b) What is the immediate precursor of B in the citric acid cycle; that is, what compound forms B as a reaction product? (c) What compound is formed from B in the citric acid cycle?arrow_forwardIn living cells, one mole of glucose undergoes a complete oxidation.(a). How many moles of ATP equivalents can be produced when one mole ofglucose is completely oxidized?(b). Indicate at which reaction steps are the ATP equivalents produced,directly or indirectly.arrow_forward
