Draw and label a lipid bilayer containing the large mitochondrial trans-membrane protein complexes representing complex I, II, III, and IV, and ATP Synthase. Label your diagrams with the correct names for the membranes, Make two more of these drawings.
Label the first one mitochondrial electron source and using a different ink color, indicate the source(s) of electrons. Label the second mitochondrial energy source, and indicate the source of energy driving the electron transport chain. In the third, label the mitochondrial electron acceptor in its proper position. Also include ATP synthase (in its correct orientation-the spherical part is on the opposite side of the membrane as the H+ reservoir). Use a different color of ink to show where the protons (H+) are pumped to drive ATP synthesis. also indicate where ATP is generated and were the power is stored to generate ATP.

An animal cell, roughly cubical in shape with side length of 10 μm, uses 109 ATP molecules every minute. assume that the cell replaces this ATP by the oxidation of glucose according to the overall reaction 6O2 + C6H12O6 →6CO2 + 6H2O and that complete oxidation of each glucose molecule produces 30 ATP molecules. how much oxygen does the cell consume every minute? How long will it take before the cell has used up an amount of oxygen gas equal to its own volume?
In phase II of ETS diagram and label the ATP synthase along with the inner mitochondrial membrane it is sitting in. Your diagram must show the intermembrane space and the mitochondrial matrix. Describe how it works step by step

- Figure 7.11 Dinitrophenol (DNP) is an "uncoupler" that makes the inner mitochondrial membrane "leaky" to protons. It was used until 1938 as a weight-loss drug. What effect would you expect DNP to have on the change in pH across the inner mitochondrial membrane? Why do you think this might be an effective weight-loss drug?arrow_forwardFigure 4.15 Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain.
