Within a mitochondrion, in what direction do protons move through ATP synthase?Group of answer choicesFrom both the cytosol and mitochondrial matrix into the intermembrane space.From the cytosol into the intermembrane spaceFrom the intermembrane space into the mitochondrial matrixFrom the mitochondrial matrix into the intermembrane spaceFrom the intermembrane space into the cytosol

6. Electron movement results in the establishment of a proton gradient across the inner mitochondrial membrane. The proton motive force then provides the energy for ATP formation. a. How are protons shifted from the matrix to the intramembrane space? b. How is the proton gradient harnessed for ATP formation? c. How does ATP reach the cellular compartment/s where biosynthesis is occurring?

Which of the following statements about the proton gradient in the mitochondria is correct?A. The proton gradient is established across the inner mitochondrial membrane.B. Protons are pumped from the mitochondrial matrix to the intermembrane space during electron transport.C. The proton gradient drives ATP synthesis through the enzyme ATP synthase.D. The energy for establishing the proton gradient comes from ATP hydrolysis.Question 5Answera.B and D onlyb.A, B, and C onlyc.A, B, C, and Dd.A and D only

In eukaryotic cells, what is the location of the ATP-synthase enzyme complex that produces most of the ATP during aerobic cellular respiration?Multiple choice question.mitochondrial matrixouter mitochondrial membraneinner mitochondrial membranecellular cytoplasm

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.
