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.

Sample Question
Which of the following are appropriate things to do when handling or yarding deer

Never separate a deer from the herd- as it is more likely to fly

Always yard deer in large groups

Make erratic movements to get them to speed up

Make sure the deer can see each other at all times

Have circular yards as deer want to get away from you and thus move fast around corners

Have a narrow race to separately safety during loading
