Self Quiz:
After watching the video (or while you are watching) try and answer these questions:
1) What happens to glucose in glycolysis?
2) Why is the NADH produced during glycolysis important?
3) What could happen to the pyruvic acid from glycolysis if there was not enough oxygen in the cell?
4) Where does the Krebs cycle take place?
5) What are the major products that come from the Krebs cycle? (HINT: there are 4 of them shown in the video)
6) What molecules from both glycolysis and the Krebs cycle are necessary for electron transport to happen?
7) Which process (glycolysis, Krebs, or electron transport) produces the most ATP?
Questions 8 and 9 are below:

Watch the McGraw Hill video below for more details on the process of electron transport. If the video doesn't play through all the way, click HERE
8) What is the purpose of the H+ ions (protons) that are being pumped into the intermembrane space of the mitochondria?
9) What is the role of ATP synthase?
