he difference between the "theoretical" and "actual" yields of ATP from oxidative phosphorylation is due to the energetic expense of:
Select one:
a. NADH oxidation
b. ADP phosphorylation
c. transporting ATP out of the mitochondria
d. transporting oxygen into the mitochondria
Option B ADP phosphorylation.
This is because, in actual state, not all H+ pass through ATP synthase to synthesize ATP. Thus energy is lost there. ATP synthesis means ADP phosphorylation at ATP synthase.

Which of the following is NOT correct about substrate level phosphorylation and oxidative phosphorylation? A. oxidative phosphorylation occurs absence of molecular oxygen B. substrate level phosphorylations use ADP as a substrate C. substrate level phosphorylations requires molecular oxygen D. both substrate level phosphorylation and oxidative phosphorylation produce ATP as a product E. substrate level phosphorylations only take place in the mitochondria I believe the answer is D, please verify & explain. Thank you
Suppose a cell is subjected to Aspirin, T4 or some other chemical uncoupler of oxidative phosphorylation, one would expect an increase in the rate of all of the following EXCEPT (2 pts) (A) ATP synthesis (B) Proton pumping by the electron transport chain (C) Heat generation by the mitochondria (D) Oxygen utilization by the cell (E) NADH oxidation by NADH dehydrogenase
Which of the following statements about oxidative phosphorylation is true? a. Oxidative phosphorylation involves the activities of the electron transport chain and the ATP synthesizing machinery. b. The oxidation of NADH is the only way to form ATP. c. ATP is synthesized using the energy that is released when electrons and hydrogen are excreted outside of the cell. d. ATP synthesis occurs during oxidative phosphorylation directly by the reduction of electron carrier proteins in the cytoplasmic membrane.
m 5 Part D Oxidative Phosphorylation n the last stage of celluler respiration, oxidative phosphorylation, all of the reduced electron cariers produced in the previous stages are oxdized by oxygen via the electron transport chain. The energy from this oxidation is stored in a form that is used by most other energy-requiring reactions in cells. From the folowing compounds involved in cellular respiration, choose those that are the net inputs and net outputs of oxidative phoaphorylation Drag each compound to...
Which two processes make up oxidative phosphorylation? A. Chemiosmosis and ATP synthesis B. Electron transport chain and chemiosmosis C. Pyruvate oxidation and electron transport chain D. Proton motive force and chemiosmosis What is the final electron acceptor in the electron transport chain? A. FADH2 B. Water C. Oxygen D. NADH
C) Define "oxidative phosphorylation." (One clear complete sentence will work as an answer.) D) The reaction ADP + Pi → ATP is highly endergonic. In the case of oxidative phosphorylation, where does the energy required for ATP synthesis come from? (Not the sun. I mean most immediately in the phosphorylation reaction itself. It's OK if this overlaps your answer to part C.) E) In terms of the energy that drives ATP synthesis, what is the difference between oxidative phosphorylation and...
The process by which ADP is converted to ATP takes place in the ___ and one of the processes by which this change occurs is known as ___. Select one: a. mitochondria/oxidative phosphorylation b. cytoplasm/oxidative phosphorylation c. mitochondria/citric acid cycle d. cytoplasm/citric acid cycle
Inhibitors of Oxidative Phosphorylation The following chemicals inhibit oxidative phosphorylation: Cyanide: Cyanide is a naturally occurring compound that binds to protein complex IV of the mitochondrial electron transport chain and prevents transfer of electrons from the protein. Metformin: At the cellular level, chemically synthesized metformin, a drug commonly prescribed for Type 2 diabetes, inhibits mitochondrial respiration by blocking complex I. Dinitrophenol: Dinitrophenol is a metabolic poison that can be sold legally as a pesticide. Although it is lethal to humans,...
How many total ATP molecules can be generated for each FADH2, assuming oxidative phosphorylation is 100 percent efficient? How many total ATP molecules can be generated for each NADH, assuming oxidative phosphorylation is 100 percent efficient? The answer choices for both questions: a. 3.3 b. 3 c. 2.5 d. 2

This is another name for Coenzyme Q. A) ubiquinone B) quantum carrier C) glutamine D) vitamin B6 39. Choose the two correct paths taken by a pair of electrons as it travels down the electron-transport chain. (1) NADH - complex / -- COQ - Complex - C C . complex...
