b. Nicotinamide Adenine Dinucleotide (NAD+)

c. Flavin Adenine Dinucleotide (FAD)

d. Coenzyme A (CoA)

10. Why is it called a cycle rather than a pathway like glycolysis?

Electron Transport Chain

11. Fill in the ETC template below with all protein complex numbers and names of important

molecules.

12. In what cycle is the majority of ATP produced? Which cycle produces the most NADH/FADH2?
