Where is ATP synthase catalytic part located in the mitochondrion? Select one: O A. outer membrane. O B. mitochondrial matrix. O C. inner membrane lipid core. O D. intermembrane space OF electron transport chain.

ATP synthesis in mitochondria requires all of the following EXCEPT (select two answers) a hydrogen ion concentration gradient across the inner mitochondrial membrane the oxidation of dinucleotide molecules that act as electron carriers fermentation of pyruvate into lactate to regenerate NAD+ the reduction O2, forming H2O the breakdown of glucose

Referring to the diagram above, where does pathway "A" occur? Where does pathway "B" occur? Remember to include BOTH prokaryotes and eukaryotes in your answer.

You treat cells with 2,4 dinitrophenol (DNP). This compound creates a temporary channel in the inner membrane of the mitochondria though the protons can move. Which of the following would you observe in these cells? Select all that apply The cells do not synthesize ATP in the presence of DNP The cells synthesize ATP in the presence of DNP The cells reduce oxygen in the presence of DNP The cells generate carbon dioxide in the presence of DNP

ATP is intermediate in the hierarchy of phosphorylated compounds with high standard free energ hydrolysis. Why is it advantageous for cells to use ATP as the "energy currency of the cell"? a. The phosphate groups transfer potential of ATP is higher than other phosphorylated compounds b. Reactions that release more free energy than ATP hydrolysis do not occur in living cells C. ATP is thermodynamically unstable but kinetically stable d. ATP can be regenerated by coupling with a reaction that releases more free energy than does ATP hyd

The figure below shows an illustration of a mitochondrian. Mustration of a mitochondrion Which of the following best describes the relationship between the structure and function of the mitochondrion? A B с D The shape of the mitochondrion Increases its material-exchange efficiency by maximiz ing its overall volume relative to its surface area. The double-membrane structure of the mitochondrion allows it to maintain its relatively acidic environment in which nutrients can be digested. The folds of the mitochondrion Inner membrane increase its material-exchange effi- ciency by maximizing its surface area relative to its volume. The specific structure of the mitochondrion Inner membrane allows it to correctly guide the folding of proteins into their functional shape.

Assume there is no cyanide poisoning. What would happen if the inner mitochondrial membrane was permeabilized to the point where it no longer served as a barrier, affecting the proton gradient and ATP synthesis?

In ATP synthase, what is the importance of the beta subunit, and how does it interact with the gamma subunit, as well as how does gamma interacts with the c ring.

Compare ATP production in the citric acid cycle to the electron transport chain, or aerobic respiration.   A. Both processes use oxidative phosphorylation.   B. Both processes use substrate-level phosphorylation.   C. The citric acid cycle uses substrate-level phosphorylation, and the electron transport chain uses oxidative phosphorylation.   D. The citric acid cycle uses oxidative phosphorylation, and the electron transport chain uses substrate-level phosphorylation.

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)
