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

identify the reactions that generate reducing equivalents that are oxidized in the mitochondrial electron transport chain to yield ATP.

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

Cytosolic NADH gives electrons over to cytosolic oxaloacetate, producing malate. This malate is then transported into the mitochondrion where it gives electrons over to mitochondrial NAD to produce NADH; which in turn gives the electrons over to the electron transport chain.TrueFalse

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.

The purpose of the electron transport chain is to A) Accumulate electrons to store energy B) Transfer electrons in order to generate ATP C) Donate electrons to change membrane potential D) All of the above
