The following image is a schematic of the metabolic processes occurring in a plant contained in a closed container. A=Light Dependent reactions B=Glycolysis C=Light Independent Reactions D=Kreb's cycle E=electron transport chain 2a) Use the figure above to explain the conditions in which the oxygen concentration remains constant in the container. b) 2-carboxyarabinitol-1,5-bisphosphate (CABP) is an inhibitor of the enzyme rubisco. Which pathway would this affect most?
NADH and succinate are substrates that can be oxidized and will consume oxygen. Rotenone and cyanide are inhibitors of the electron transport chain and can block oxidation. Match each description of the effector to the appropriate oxygen consumption. A plot may match more than one description. Some plots will not match any description. (At least one of the matches in the image was incorrect)
The primary role citric acid cycle is to collect high energy electrons from the oxidation of carbons in the form of NADH and FADH2. If the electron transport chain is inhibited, would you expect the citric acid cycle to be more active or lessactive? Explain your answer.
Cancer cells need more DNA synthesis but the NADPH/ NADP* ratio is high. Which of the following statement is TRUE? Flux through the oxidative reactions is low and the nonoxidative reactions are reversed in order to form ribose 5-phosphate. O b. The oxidative reactions and the isomerase supply both ribose 5-phosphate and NADPH with little flux through the nonoxidative branch. O C. Flux through the oxidative reactions increases and ribose 5-phosphate is shunted into glycolysis by the nonoxidative reactions. Od. The ribose 5-phosphate is recycled through the oxidative steps via the nonoxidative reactions and gluconeogenesis.
To learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs. These drugs can each pick up electrons from specific intermediates in the pathway as shown above. You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table. In the presence of drug A Will the cells continue to consume O2? (Yes or No), Will the cells continue to produce CO2? (Yes or No) In the presence of drug B Will the cells continue to consume O2? (Yes or No), Will the cells continue to produce CO2? (Yes or No)
Rotenone is an insecticide that is not toxic to plants, but is highly toxic to fish and insects. (it will also kill mammals, but it doesn’t easily get into our cells). When Rotenone is added to cells in vitro, ATP production stops, oxygen is no longer reduced and NADH builds up. Based on these results, explain what is a possible mechanism of action for Rotenone?
Cytochrome P450 (CYP450) monoxygenase is the enzyme involved in Phase I metabolism. 450 refers to: * It can metabolize 450 drugs when in the reduced form and complexed to carbon monoxide It can produce 450 drugs when in the oxidized form and complexed to carbon dioxide It can emit light at 450 nm when in the oxidized form and complexed to carbon monoxide It can absorb light at 450 nm when in the reduced form and complexed to carbon dioxide It can absorb light at 450 nm when in the reduced form and complexed to carbon monoxide
The electron transport train relies on electron carriers NADH and FADH2 to function normally. An experiment was conducted to determine the efficiency of both carriers. In the first trial, NADH was removed, and in the second trial, FADH2 was removed. If both trials were given the same amount of substrate, which is likely to produce more energy and why? Include the role of the various ETC complexes.
A cell is grown on minimal media containing only 3-phosphoglyceric acid as a source of carbon and energy. What is the most likely place this compound would enter the metabolic cycle? O Glycolysis O Conversion of Pyruvate to Acetyl-CoA O The TCA Cycle The Electron Transport Chain
In oxidative phosphorylation.... 1. Succinate contributes 2e- to Complex II and 2H+ to the mitochondrial proton gradient. 2. NADH in the matrix passes 2 e- to coenzyme Q via Complex I. 3. Complexes I, II, III, and IV each contribute to the matrix proton gradient. 4. O2 stabilizes the catalytically active conformation of Complex V. 5. Reversible protonation of c subunits leads to rotation of the Complex V gamma subunit. 6. Each β subunit can bind ATP tightly under the right conditions. 7. For every 3 protons that pass across the inner mitochondrial membrane, 1 ATP is produced. Choose all options that are true.
Of eight enzymes in the CAC, why is the succinate dehydrogenase complex unique? Because it is a component of the electron transport chain Because it catalyzes an oxidative reaction Because it is an integral membrane protein All of the above Only A and C
Consider the reaction catalyzed by PFK. In the presence of ATP, which of the following will be expected? Select all that apply. The T-state is stabilized The rate of the reaction is enhanced. The initial velocity plot would show a shift in the curve to the right The quaternary structure of PFK is stabilized to promote efficient binding of substrate
