Which statement about oxidative phosphorylation is NOT true?Group of answer choicesIt generates ATP using energy provided by the respiratory electron transfer chain.It requires aerobic conditions.It takes place in the cell's cytosol.It requires a proton motive force.It is powered by NADH and FADH2 produced by the tricarboxylic acid (TCA) cycle.

Which of the following statements about substrate-level phosphorylation is FALSE?Group of answer choicesThe oxidation of intermediate metabolic compounds releases energy that is used to generate ATP.It involves the direct transfer of a high-energy phosphate group from an intermediate metabolic compound to ADP.It occurs in the Krebs cycle.No final electron acceptor is required.It occurs in glycolysis.

Which of the following is the best definition of oxidative phosphorylation?Group of answer choicesElectrons are passed through a series of carriers to O2.ATP is directly transferred from a substrate to ADP.Electrons are passed through a series of carriers to an organic compound.A proton gradient allows hydrogen ions to flow back into the cells through transmembrane protein channels, releasing energy that is used to generate ATP.

A molecule enters a cell and creates pores in the inner mitochondrial membrane. How will ATP generation as a result of oxidative phosphorylation be affected? A.Increased, because the cell membrane is still complete and proton movement is increased.B.Increased, because ATP is required for cell function and this cell’s mitochondria will need to work harder.C.Decreased, because there is no available oxygen.D.Decreased, because the proton gradient will be dissipated.

Which of the following statements about the electron transport chain and ATP production in the mitochondria is false?Group of answer choicesAny drug that inhibits the ATP synthase will also inhibit the flow of electrons in the ETC.For oxidative phosphorylation to occur, it is essential to have a membrane that is impermeable to protons except through specific proteins pores or protein complexesThe yield of ATP per mole of fuel depends on the type of molecule being catabolized.Some complexes of the respiratory chain pump protons into the matrix to create an electrochemical gradient.Exergonic electron transfer provides the energy for proton pumping.
