Unformatted text preview: transferred to FMN and then to Fe-S cluster, and then to Q. However, you should understand why electrons have to be transferred from NADH to FMN first and why not directly to Fe-S clusters. Understand why reduction of Q to QH2 can be coupled with the uptake of two protons from the matrix. Know what is the complex II (the electron donor and the electron acceptor). Again, why electrons have to be transferred to a flavin before they are transferred to Fe-S clusters. Know that electrons from complex I do not go through complex II. Both complex I and complex II are used to reduce coenzyme Q, but the initial electron donors are different (NADH vs succinate). Understand why oxidation of FADH2 ALWAYS yield fewer ATPs than oxidation of NADH Know the electron carriers in complex III (heme, Fe-S clusters). NO need to memorize the names of the heme proteins except cytochrome c. Understand what is a Q cycle and the relationship between Q cycle and proton pumping...
