false

2.  What does the electron transport chain use to produce many more molecules of ATP?

NADH and NADH2

3.  Where do the proteins of the electron transport chain reside?

They reside in the inner membrane

4.  When electrons are passed from protein to protein they give up a bit of their energy. What do the proteins in the chain do with that energy?

Pump hydrogen ions

5.  Answer the “check your understanding” question and write the full correct answer below:

To provide the energy that pumps protons across the inner membrane of the mitochondria

6.  Answer the “check your understanding” question and write the full correct answer below:

The difference in concentration of a molecule between two side of a membrane

7.  Why is the oxygen we breathe essential to electron transport?

Oxygen captures the electrons, combines with hydrogen, then forms water

8.  What does oxygen combine with aside from electrons? ___Hydrogen ____ what does it become? _water______

9.  Sketch the picture of the mitochondria and the gray dots representing where the H+ build up like “water behind a dam.”

10.  Answer the “check your understanding” question and write the full correct answer below.

To provide the power to make ATP

11.  What happens to the chain if there is a lack of oxygen?

The proton gradient would disappear

12.  What happens to NAD+ and FAD+ when they are done at the electron transport chain?

they disappear

13.  Answer the “check your understanding” question and write the full correct answer below:

to capture energy contained in the bonds of glucose in molecules of ATP

14.  Sketch out the 5 series of steps summarizing the passing off of energy from glucose through the end.

15.  Answer the “check your understanding” question and write the full correct answer below:

The bonds of the glucose molecules

16.  Answer the “check your understanding” question and write the full correct answer below:

It blocks the oxygen so the oxygen cannot accept electrons from the electron transport chain
