Solve it asap with explanation he othe acid cycie, and B is the site where protons aCcumulate as aresult of the electron transport chalin.50Which best describes the role of FADH2 in aerobic metabolism?FADH2 is a proton shuttle and transports high energy protons to the electron transport chain.FADH2 is an electron shuttle and transports high energy electrons to the eiectron transport chain,FADH2 is a high energy molecule that directly fuels nearly all cellular work.FADH2 picks up electrons from the electron transport chain and brings them to the citric acid cyde.51Which of the following is true when there is no oxygen (02) avalable?

pH and in the Chloroplast Proton-Motive Force (Integrates with Chapter 20.) In mitochondria, the membrane potential () contributes relatively more to p (proton-motive force) than does the pH gradient (pH). The reverse is true in chloroplasts. Why do you suppose that the proton-motive force in chloroplasts can depend more on pH than mitochondria can? Why is () less in chloroplasts than in mitochondria?
Put the following pathways in the order they occur during aerobic respiration. a. electron transfer phosphorylation b. acetylCoA formation c. citric acid cycle d. glycolysis
Where in cellular respiration does feedback inhibition occur? Describe all. (Hint:think about glycolysis, pyruvate processing, and electron transport chain and what's being inhibited in each) What would happen if this feedback inhibition were removed?
A suspension of inside-out submitochondrial particles (i.e., the F1 unit is on the outside of the particle) is placed in a solution that contains ADP, Pi, and NADH. Will increasing the proton concentration of the solution result in ATP synthesis? Explain.
DRAW IT The graph here showsthe pH difference across theinner mitochondrial membraneover time in an actively respiringcell. At the time indicated by thevertical arrow, a metabolic poisonis added that specifically andcompletely inhibits all function ofmitochondrial ATP synthase. Drawwhat you would expect to see forthe rest of the graphed line, andexplain your graph.
Show how the reactions of the electron transport chain differ from those in Question 3 when FADH2 is the starting point for electron transport. Show how the reactions that liberate enough energy to drive the phosphorylation of ADP differ from the pathway when NADH is the starting point
6. The lens of the eye si the light refracting medium of the eye, and ti has no mitochondria. Glucose is used sa an energy source ni the lens. Which metabolic pathway of glucose supplies energy to the crystalline eye lens? To answer the question: a) write a diagram of the metabolic pathway that provides the eye's lens with ATP, specify enzymes and coenzymes; b) mark the reactions associated with the ATP consumption and synthesis, calculate the ATP yield during the process; )c specify the mechanisms ofATP synthesis ni the process; d)name the tissues and cells in which the ATP synthesis is the same as in hte lens; e) writethe dehydrogenation reaction and the reactionoffinal product formation occurring in the process;
The proton motive force is the result ofa. ATP synthase transporting protons during ATP synthesisb. an electron gradient between the matrix and the intermembranespace of a mitochondrionc. a proton gradient between the matrix and intermembrane space ofa mitochondriond. a buildup of negatively charged ions
Assuming all the NADH+H+ and FADH2 are used for oxidative phosphorylation, how many net ATP are made from 1 molecule of glucose? (hint: don’t forget to also include substrate level phosphorylation)
You are growing human muscles cells in the lab and you are trying to test how wellthe cells survive with decreasing concentrations of oxygen. As part of yourexperiment, you are measuring the rate of glucose use, the rate of mitochondrial ATPproduction and the pH of the solution surrounding the cells. As the concentration ofoxygen becomes lower änd lower, what changes might you expect to observe inthese cells?A. The rate of glucose use would increase, the rate of mitochondrial ATP productionwould decrease, and the pH of the solution would decrease (become more acidic).B. The rate of glucose use would decrease, the rate of mitochondrial ATP productionwould decrease, and the pH of the solution would increase (become more basic).C. The rate of glucose use would increase, the rate of mitochondrial ATP productionwould increase, and the pH of the solution would decrease (become more acidic)D. The rate if glucose use would decrease, the rate of mitochondrial ATP productionwould decrease, and…
You experiementally apply the compund antimyctin, which inhinits the functioning of complex III, cytochrome reductase, from participating in redox reactions. You follow this with the addition of 6 molecules of FADH2. How many total ATP molecules can be created using the number of protons that were pumped?
If glycolysis has an overall –DG (i.e., it’s exergonic), why does it require an energy investment of two ATP to happen?
