Sample Question
What would happen if there was a mutation to Complex I and Complex II of the electron transport chain of cellular respiration so that it could not oxidize NADH?

The proton gradient would not form because the electrons from NADH could not be obtained. No ATP synthesis would occur.

The proton gradient would be created more rapidly since NADH would donate its electrons more readily. ATP synthesis would increase.

The electrons would still pass from Complex III and Complex IV to create a smaller proton gradient. Not as much ATP could be made.

The protons from the matrix would have to diffuse through the membrane to maintain the proton gradient needed for ATP synthase.

Electrons from the proton gradient would be donated to Complex I so that it could function normally.
