32 views8 pages

Document Summary

By the end of this topic, you should be able to: Describe the five types of electron carriers found in the mitochondrial electron transport chain. Explain how electrons flow between complexes of the electron transport chain, and ultimately to o2. State how many protons are pumped out of the matrix for each reduced electron carrier that donates electrons to the electron transport chain. Explain how energy flows from reduced electron carriers to atp in the process of oxidative phosphorylation. Explain the fundamental mechanism of atp synthase, without memorizing the roles of individual subunits. State the number of protons that move across the inner mitochondrial membrane to synthesize and export one atp molecule, and justify that number. Calculate how much atp can be obtained by aerobic or anaerobic metabolism of one molecule of glucose. Predict the effects of inhibiting elements of the oxidative phosphorylation system. In the citric acid cycle, two carbons are oxidized to co2 to reduce the electron carriers.
