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.

Which of the following best describes substrate level phosphorylation?ANSWERIt is the same as oxidative phosphorylation.It occurs when an enzyme transfers a phosphoryl group from a donor substrate directly to ADP to make ATP.It occurs when light energy is used to activate electrons.It occurs during active electron transport.

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.

The electron transport chain results in the generation of:A.a proton concentration gradient across the inner mitochondrial membrane, which drives phosphorylation of ADP.B.a proton concentration gradient across the inner mitochondrial membrane, which reduces NAD+ in a coupled reaction.C.an electron concentration gradient across the inner mitochondrial membrane, which drives phosphorylation of ADP.D.an electron concentration gradient across the inner mitochondrial membrane, which drives oxidation of NADH in a coupled reaction.Submit

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.
