A person is born with a mutation that causes their cells to not have the ability to produce the NADH dehydrogenase complex, the complex that allows the electron transport chain to make ATP from NADH. Will this patient be able to produce any energy at all from the ETC? No-there are no other molecules the ETC uses Yes-FADH2 can still enter the ETC No-NADH is necessary for the ETC Yes-NAD+ can still enter the ETC
