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.

Which of the following statements about the electron transport chain in mitochondria is NOT correct? A) Electrons increase their free energy at each step along the transport chain B) The final electron acceptor is oxygen C) Transporters alternate between reduced and oxidized states by accepting and donating electrons D) Electron transporters are associated with the inner mitochondrial membrane E) Electrons transported along the chain come from NADH and FADH2 molecules

Which process results in the greatest amount of ATP?Group of answer choicesThe activity of the electron transport system in the Golgi apparatusThe activity of the electron transfer system in the mitochondriaKrebs cycleGlycolysis

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.

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

Which of these biochemical processes would you expect to liberate the most ATP?a) Gluconeogenesisb) Fatty acid synthesisc) Glycolysisd) Beta oxidatione) Electron transport chain activity
