1) The final electron acceptor in cell respiration is

i) Oxygen
ii) Cytochrome c
iii) NAD+
iv) ATP

2) The reactions of glycolysis produce how many total ATP molecules?

i) 1
ii) 3
iii) 4
iv) 2

3) The Krebs cycle produces how many NADH molecules for 1 glucose molecule?

i) 3
ii) 4
iii) 6
iv) 2

4) ATP synthase is

i) A multiple subunit, transmembrane protein complex
ii) All of the above
iii) An enzyme
iv) A hydrogen channel

5) If a bacterial cell were exposed to a bacteriacidal agent that degraded proteoglycans, what affect (if any) would this have on fermentation?

i) Fermentation would function normally in this case
ii) Fermentation would halt due to the accumulation of NADH
iii) Fermentation would stop because H+ ions would not establish a gradient
iv) Fermentation would speed up because glucose would enter the cell more rapidly.
