Imagine an organism with mutations in complexes I, III, and IV that prevent pumping of hydrogen ions into the intermembrane space but still allow electrons to pass through the electron transport chain. Which of the following is the most likely consequence of these mutations?
a. the mobile electron carriers q and cyt c will no longer pass electrons through the electron transport chain.
b. oxygen will not accept electrons and combine with 2 h+ to form water at the end of the electron transport chain.
c. atp synthase will not convert adp to atp.
d. nadh and fadh2 will not donate new electrons to the electron transport chain
