Question

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? The mobile electron carriers Q and Cyt c will no longer pass electrons through the electron transport chain. Oxygen will not accept electrons and combine with 2 H+ to form water at the end of the electron transport chain. ATP synthase will not convert ADP to ATP. NADH and FADH2 will not donate new electrons to the electron transport chain

Answer 1

Answer:

ATP synthase will not convert ADP to ATP

Explanation:

ATP synthase taps on the protonmotive force created during the Krebs cycles when cytochromes, as they pass electrons,  pump protons into the intermembrane spaces of the  mitochondria. As the protons move back to the matrix the ATP synthase uses this potential energy to converts ADP to ATP.
