- What thermodynamic force drives the transport of ADP and Pi into the mitochondrial matrix for ATP synthesis?arrow_forwardA new weight loss drug, Super Fat Melter, is introduced on the market but then quickly recalled after a few patients die. As it turns out, the pill makes the lipid bilayer of the inner mitochondrial membrane leaky to H+. What impact does this have on ATP production? Explain, with reference to the type of phosphorylation affected.arrow_forwardWhich directions across the mitochondria must H+, ATP, ADP, and Pi travel during active mitochondrial ATP synthesis?arrow_forward
- What happens to the proton gradient across the mitochondrial inner membrane if electron flow through the ETC stops?arrow_forwardWhen the antibiotic X is added to actively respiring mitochondria, several things happen: the yield of ATP decreases, the rate of O2 consumption increases, heat is released, and the pH gradient across the inner mitochondrial membrane increases. Does X act as an uncoupler or an inhibitor of oxidative phosphorylation? Explain the experimental observations in terms of the antibiotic’s ability to transfer K+ ions across the inner mitochondrial membrane.arrow_forwardWhat are two advantages of the components of the electron transport chain being embedded in the inner mitochondrial membrane?arrow_forward
- Why does mitochondrial NADH yields more ATPs than cytosolic NADH?arrow_forwardTwo mobile electron transfer carriers are present in the inner mitochondrial membrane. Name these two carriers.arrow_forwardThere are some drugs that can inhibit the activity of ATP synthase. How does this affect the pH of the inner membrane space and the mitochondrial matrix?arrow_forward
- What are some of the difficulties in determining the exact number of protons pumped across the inner mitochondrial membrane by the respiratory complexes?arrow_forwardIn the 1930s, some physicians prescribed low doses of a compound called dinitrophenol (DNP) to help patients lose weight. This unsafe method was abandoned after some patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+ . Explain how this could cause weight loss and death.arrow_forwardWhat is the role of each of the following in the electron transport chain: (a) FADH 2; (b) ADP; (c) ATP synthase; (d) the inner mitochondrial membrane?arrow_forward
