Similar to the activity in our muscle cells, certain bacteria canutilize sugars by aerobic cellular respiration (which requiresoxygen) or by fermentation (which does not). However, like musclecells, these bacteria only use fermentation when oxygen is notavailable. Why is aerobic respiration preferable? What is thespecific role of oxygen in this process?
Considering the chemicalequation of the aerobiccellular respiration whichmolecules does the cell needand which molecules does itliberate in the process?
(a) Starting with one molecule of glucose, how many ATPs are produced during (I) aerobic and (II) anaerobic respiration? (b) In chemiosmotic (oxidative) phosphorylation, what is the most direct source of energy that is used to convert ADP + Pi to ATP and what the driving force for the ATP formation through ATP synthase?
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…
NADH can eventually lead to the formation of 3 or 5 ATP molecules. What processdetermines how many ATP molecules are formed? Explain briefly.
The first pathway of cellular respiration is glycolysis. The net gain of this pathway is: A) 2 ATP, 0 NADH, 4 pyruvate B) 2 ATP, 2 NADH, 2 pyruvate C) 4 ATP, 4NADH, 2 pyruvate D) 4 ATP, 2 NADH, 2 pyruvate E) 0 ATP, 2 NADH, 4 pyruvate
Which step(s) of cellular respiration would be directly inhibited by high concentrations of NADH? How would this affect other steps of cellular respiration?
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?
During aerobic respiration how many ATP molecules are produced by theoxidation of a single molecule of pyruvate?
Chemiosmosis and the electron transport chain are critical to the generation of ATP for both aerobic and anaerobic respiration. What is happening at this final step in ATP generation? Name the proteins, co-enzymes and enzymes involved.
Cyanide causes an irreversible inhibition of electron transport that prevents ATP synthesis, whereas the inhibitoryeffect of small amounts of dinitrophenol on ATP synthesisis reversible. Explain the difference.
Which of these process is a common step that happens before both aerobic respiration and anaerobic respiration? A) citric acid (Krebs) cycle B) glycolylcle C) electron transport chain D) All of the above
