Cellular Respiration: Aerobic Harvest of Food Energy 
 
Chapter Content: Fermentation: Anaerobic Harvest of Food Energy 
 
Complete the following questions as you read the chapter content—Fermentation: 
Anaerobic Harvest of Food Energy: 
1. Fermentation is essentially glycolysis because glycolysis does not require oxygen to function. 
 
2. What is the one characteristic shared by aerobic cellular respiration, lactic acid 
fermentation, and alcoholic fermentation? 
 
a. They all do not use O2 to make ATP. 
 
b. They all use lactic acid to make ATP. 
 
c. They all use O2 to make ATP. 
 
d. They all use glucose to make ATP. 
 
 
3. Fill in the following table regarding the harvesting of energy from food.

4. In lactic acid fermentation, __________ becomes the target of reduction by NADH. 
 
a. ATP 
 
b. lactic acid 
 
c. glucose 
 
d. pyruvic acid 
 
 
5. Use Figure 6.16 on pg. 103 of your textbook to answer the following questions: 
 
a. How long ago did the first eukaryotic organisms appear? 2 billion years ago. 
 
b. How long ago did atmospheric oxygen first appear? 2.45 billion years ago. 
 
c. How long were prokaryotes present on Earth before eukaryotes arose? 1.5 billion years. 
 
 
Major Theme Connection: 
6. You own a winery in Napa Valley. An assistant accidentally leaves the lid for a vat of wine 
slightly ajar. Would the yeast inside continue to perform alcoholic fermentation? Briefly 
explain your answer with some details about what would happen. 
 
No, because they would be exposed to atmospheric oxygen and they would preferentially perform 
aerobic respiration. 
 
 
 
 
 
 
Common Thread Connection: 
7. You are obviously still breathing during an anaerobic activity like sprinting. If the skeletal 
muscle cells in your legs are performing lactic acid fermentation to produce the necessary 
ATP for their proper functioning, what is happening to the O2 gas you are breathing? 
 
 The O2 is being used to power the cellular respiration occurring everywhere else in your body.
