11.  In this section you will be able to identify the functions of some components shown below, given different options. Resources

12. Incorrect The function of complexes I, III, and IV is to: transport electrons from the outer mitochondrial space to the inner mitochondrial space transport electrons from the inner mitochondrial space to the outer mitochondrial space Correct Incorrect maintain a higher concentration of protons in the outer mitochondrial space maintain a higher concentration of protons in the inter mitochondrial space Resources

13. Correct Incorrect The function of cytochrome C is: The pumping of protons from complex III to complex IV The transfer of electrons from complex III to complex IV Incorrect The transfer of electrons from complex I to complex III The transfer of electrons from complex IV to ATP synthase Resources
