Does electron transport stop if rotenone is added? Which of the following explains the reasoning?
A)Yes,there is not an electron source.
B)No,rotenone is not strong enough to inhibit all of the electron-transport chain.
C)No,there is still a source of electrons from Complex II.
D)Yes,rotenone inhibits Complex III;therefore,electrons cannot be passed on.

Question

Quizplus · Accepted Answer

Rotenone specifically inhibits Complex I of the electron transport chain, not Complex III as stated in option D. However, electrons can still enter the electron transport chain through Complex II, which is not affected by rotenone. This allows for the continuation of electron transport and ATP production, albeit at a reduced rate.
