1.___ Which of these processes occurs in the cytosol?

A) the citric acid cycle B) glycolysis

C) the electron transport system D) the preparation of pyruvate E) chemiosmosis

2. ___ Which is NOT an end product of eukaryotic cellular aerobic respiration?

A) carbon dioxide B) water

C) ATP D) oxygen E) All of the choices are correct

3. ___ Complete oxidative breakdown of glucose results in ______ ATP molecules.

A) 2 B) 4 C) 32 D) 36 E) 39

4. ___ Why would an organism utilize fermentation if it was wasteful of the energy in food molecules

and posed the threat of killing itself with high levels of toxic alcohol?

A) The organism can survive short spells of anaerobic conditions and maintain growth and

reproduction.

B) If glucose levels are not high, there may be time to disperse the alcohol "waste"

C) Fermentation can provide a rapid burst of ATP since it does not have to go through the full

breakdown cycle

D) All of the choices are advantages

E) None of the choices is an advantage; anaerobes only survive where aerobes cannot

5. ___ The correct sequence for aerobic metabolic breakdown of glucose is

A) glycolysis--preparatory reaction--cirtric acid cycle--electron transport system

B) preparatory reaction--glycolysis--electron transport--citric acid cycle

C) electron transport system--citric acid cycle--preparatory reaction--glycolysis

D) light reactions--electron replacement--ATP production--calvin cycle

E) glycolysis--citric acid cycle--electron transport system--preparatory reaction

6. ___ The primary energy carrier between the citric acid cycle and the electron transport system is

A) NADH B) ADP C) FADH2 D) H2O E) CO2

7. ___ Of the following processes, which does NOT require oxygen to occur?

A) electron transport system B) preparatory

C) glycolysis D) citric acid cycle E) All of these require oxygen

8. ___ The preparatory reaction breaks

A) glucose into pyruvates B) pyruvates into glucose

C) pyruvates into acetyl-CoA and carbon dioxide D) pyruvates into acetyl-CoA and water

E) acetyl CoA into pyruvates and carbon dioxide

9. ___ The carbon dioxide we exhale is produced in

A) glycolysis. B) the electron transport system

C) lactate fermentation. D) the citric acid cycle E) the Calvin cycle

10. ___ Which process produces alcohol or lactate?

A) the citric acid cycle B) glycolysis C) the electron transport system

D) fermentation E) the preparatory reaction

11. ___ The large number of ATPs produced are

A) embedded in the cristae membranes and diffuse both directions.

B) inside the mitochondria matrix and diffuse out through the membrane

C) inside the mitochondria matrix and leave through a channel protein

D) outside the mitochondria and diffuse in through the membrane

E) outside the mitochondria and enter through a channel protein

12. ___ One turn of the citric acid cycle produces

A) 2 NADH, 2 FADH2, 2 ATP B) 3 NADH, 1 FADH2, 1 ATP

C) 1 NADH, 3 FADH2, 2 ATP D) 3 NADH, 2 FADH2, 1 ATP E) 3 NADH, 1 FADH2, 2 ATP
