4. Question 5 The 2 carbons in acetyl–CoA are eventually used to form —
Glucose
ATP
Pyruvate
Oxaloacetate
Carbon dioxide
Bloom’s level: Knowledge/Understanding

5. Question 6
All of the glycolysis reactions do not require oxygen and can take place in an anaerobic environment.
This is true
This is false
Bloom’s level: Knowledge/Understanding

6. Question 7 What is the function of the coenzymes, NADH and FADH2 ?
Charging electrons to power ATP synthase
Catalyzing the formation of acetyl-CoA
Providing electrons and H+ to the electron transport chain
Transporting CO2 into the mitochondria
Acting as a terminal electron acceptor
Bloom’s level: Knowledge/Understanding

7. Question 10 Lactic acid fermentation is an anaerobic process?
This is true
This is false
Bloom’s level: Knowledge/Understanding

8. Question 11
The theoretical ATP yield is 38 for prokaryotes and 36 for eukaryotes. Why is there a difference?
2 ATPs are used during glycolysis for prokaryotes but not eukaryotes
The Krebs cycle only occurs in eukaryotes
No FADH2 is produced in prokaryotic respiration
NADH made during glycolysis must be transported into the mitochondria of eukaryotes.

9. Question 12
An experimental drug blocks the decarboxylation reactions that convert pyruvate into acetyl-CoA. A cell treated with this drug would not be able to complete glycolysis.
This is true
This is false
Bloom’s level: Application

10. Question 13
When making wine, grape juice and yeast are sealed into a container. Why must the container be air tight?
To prevent the buildup of lactic acid
Fermentation only occurs in the absence of oxygen
Yeast cannot live in aerobic environments
To prevent the yeasts from dying
To increase the production of acetyl-CoA

13. Question 16
What happens to the electron’s energy as it moves through the electron transport chain?
The electrons gain energy through each transfer
The electrons lose energy through each transfer
The energy content is unchanged
The energy drops to a different orbital
Bloom’s level: Application

14. Question 17
During a heart attack blood flow to the cardiac muscle is restricted. How would this affect cellular respiration?
ATP production would be increased
ATP production would remain unchanged
ATP production would be decreased
The cell would switch to alcohol fermentation
