CHEM 210 Module 8 Exam Newest
1. What is the "unifying" theory covered in this module?: Chemiosmotic theory
2. How many ATP are produced per NADH molecule? Per FADH2 molecule?: -
NADH produced 2.5 ATP, while produces FADH21.5 ATP.
3. What happens to the carbon skeleton of an amino acid after it is separated
from NH4+?: The carbon skeleton becomes acetyl-CoA, then ATP.
4. Why is urea such a good molecule for excreting nitrogen from cells?: It has
a high density of nitrogen in a small molecule, and it can form numerous hydrogen
bonds with water.
5. What is an integral protein?: A protein firmly embedded in the lipid bilayer
1/4
, 6. How many complexes are in the ETC?: Four complexes named complex I, II,
III, and IV
7. At which ETC complex is H2O produced? How is it produced?: At complex
IV by the following reaction: O2 + 4e- + 4H+ ’ 2H2O
8. What complex oxidizes NADH? How about FADH2?: Complex I for NADH.
Complex II for FADH2.
9. At which complex is water produced from oxygen?: Complex IV
10. How is the H+ gradient formed?: Complexes I, III, and IV pump these ions from
the matrix to the intermembrane space.
11. What is the purpose of FO and F1 in ATP synthase?: FO contains the pore
through which H+ ions flow causing its rotation. The rotation of FO causes F1 to
catalyze the formation of ATP from ADP and Pi.
