A scientist is studying the catabolism of glucose in a particular strain of bacteria. Normally, that species of bacteria produces 10 NADH, 2 FADH2, and 4 ATP from the theoretical net yield of a single glucose molecule. They calculates that the theoretical net yield is only 2 ATP and 4 NADH in this strain. Provide an explanation for what is happening and why. Use the different parts of cellular respiration in all parts of your explanation.

Can you please explain the relationship of ATP concentration and NADH concentration in this graph (cellular respiration)? At different treatments of ATP (E.g. At 25 ATP, 50 ATP, 100 ATP), why did the NADH concentration change?
Compare the reactants, products, and energy yield of the 3 stages of cellular respiration. (You are NOT responsible for all the intermediate steps. For example: know that glucose is split into 2 molecules of pyruvate in glycolysis, 2 net ATPs are produced and 2 NADH pick up energy that will be used in the final step of cellular respiration).
What is the direct mechanism of ATP synthesis during the electron transport phase of cellular respiration? (what is the potential energy source that drives ATP production?) b) Why is oxygen needed for this phase? c) What is the role of ATP synthase
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
In the absence of oxygen the cell will perform only glycolysis, and not the rest of respiration. Is this efficient? How much of the energy has been harvested from glucose at this point
Why is there a difference in the ATP that is being produced by the NADH molecule coming from Glycolysis which could be 4-6 for 2 NADH molecules? a.The conversion of reduction of NAD+ to NADH is a highly energetic process. b.Glycolysis uses 2 ATP for the production of NADH. c.NADH molecules from Glycolysis is not energetic enough to produce the 3 ATP. d.It will be dependent on the pathway that the NADH will be undergoing.
which of the following woudl decrease the number of atp molecules generated per nadh molecule in the electron transport chain? a. increasing the energy of the electrons nadh transfer to complex I b. reducing the number of protons required by ATP synthase to produce an ATP moelcule c. having nadh transfer its elections to complex III instead of complex I d. increasing the amount of oxygen available to the cell
When oxygen is unavailable, some cells use anaerobic (fermentation) pathways to make ATP. Another textbook says regarding fermentation: "The final steps serve only to regenerate NAD+." What does this statement mean? Explain using examples of specific fermentation pathways.
At the end of cellular respiration, how many molecules of NADH are there? Group of answer choices a)2 b)6 c)0 d)4 e)8
In this question, I'd like you to think about what would happen if we applied an herbicide that prevented plant growth by inhibiting some of the pieces in your diagram above. For example, if we applied an herbicide to our plants and it affected the ability of Photosystem II to work, it would prevent he production of oxygen. Let's say we apply an herbicide to our plants and it affects the function of ATP synthase. What product would be inhibited? Group of answer choices ATP NADPH G3P Oxygen
Imagine a scenario in which a cell has no oxygen and pyruvate is absent, and therefore, NADH can't transfer hydrogens back to pyruvate. What will happen to glycolysis? Explain your answer.
Which of the following statements is TRUE of the electron transport chain (ETC)? A. The movement of electrons down the ETC drives the formation of a proton (H+) gradient. B. The movement of H+ ions through ATP synthase drives the transfer of electrons down the ETC. C. The movement of electrons down the ETC drives the movement of ADP and phosphate through ATP synthase. D. The movement of H+ ions across the inner membrane of the mitochondria drives the transfer of electrons down the ETC.
