PREDICT Could the inner mitochondrial membrane carry out its functions in the coupling of electron transport and ATP synthesis if its lipid bilayer were readily permeable to hydrogen ions (protons)?
21. The heart of Peter Mitchell’s theory of chemiosmosis implies that the connection betweenelectron transport and the synthesis of ATP is indirect. Explain this statement.
Although the outer mitochondrial membrane is permeable to all small molecules, the inner mitochondrial membrane is essentially impermeable in the absence of specific transport proteins. Consider this information answer: If the inner mitochondrial membrane were rendered as permeable as the outer membrane, how would that affect oxidative phosphorylation? Which specific processes would stop and which remain?
BIOC 384 Mitochondrial Electron Transport Q11.3: What explains the observation that FADH2 oxidation yields one less ATP than NADH oxidation by the Electron Transport System?
If isolated mitochondria are incubated with asource of electrons such as succinate, but without oxygen,electrons enter the respiratory chain, reducing each of theelectron carriers almost completely. When oxygen is thenintroduced, the carriers become oxidized at different rates(Figure Q14–1). How does this result allow you to order the electron carriers in the respiratory chain? What is theirorder?
According to the chemiosmotic theory, what would be theeffect on oxidative phosphorylation of allowing otherpositive ions to diffuse across the inner mitochondrialmembrane?
12. Explain why those biological reactions that have their equilibria shifted towards theproducts have negative values for ΔGo of reactions. Explain how equilibria relates toGibbs free energy.
How are the mitochondrion and the hydrogenosomesimilar structurally? How do they differ? How do theydiffer metabolically?
A 70-kg adult human (154 lb) could meet his orher entire energy needs for one day by eating 3 moles ofglucose (540 g). (We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.
Considering the chemicalequation of the aerobiccellular respiration whichmolecules does the cell needand which molecules does itliberate in the process?
9. Protons usually move across membranes (by active transport) in all of the following directions except: from the mitochondrial matrix, across the mitochondrial cristae, into the intermembrane space B. from the Halobacterium halobium cytosol, across the plasma membrane, into the extracellular fluid C. from the cytosol of plant cells, across the vacuolar membrane, into the central vacuole D. from the cytosol of skeletal muscle cells, across the plasma membrane, into the extracellular fluid from the lysosome of animal cells, across the lysosomal membrane, into the cytosol
Assuming that the pH of the IMS is 1.4 units lower than the pH of the matrix, the free energy yield associated with the transport of a proton from the mitochondrial intermembrane space (IMS) to the mitochondrial matrix is △ G of the reaction is 8.310 KJmol-1 What is the minimum number of protons that must enter the mitochondrial membrane from the IMS in order to synthesize one molecule of ATP?
