Fermentation

Question 1

What is fermentation and how does it differ from cellular respiration?

Answer 1

Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose

Question 2

What are the two types of fermentation? How are their products the same and how are their products different?

Answer 2

Alcoholic and Lactic acid. Lactic acid fermentation produces lactic acid, while alcoholic fermentation produces ethanol and carbon dioxide.

Question 3

Is fermentation considered an aerobic or anaerobic process?

Answer 3

Anaerobic, no oxygen.

Question 4

Where does fermentation take place within a cell?

Answer 4

Cytoplasm

Question 5

What is a scenario in which your cells may need to switch from cellular respiration to lactic acid fermentation? Explain.

Answer 5

When the body needs a lot of energy in a short amount of time.

Question 6

How much ATP energy can be generated from fermentation?

Answer 6

Two ATP molecules

Question 7

Which process is more efficient at generating ATP: cellular respiration or fermentation? Explain.

Answer 7

Cellular respiration. This is due to its aerobic environment and its ability to fully use oxygen to break down glucose completely. It also produces more ATP.
