Aerobic & Anaerobic Cellular Respiration

Question 1

Which is more efficient (makes more ATP for one glucose)? How much?

Answer 1

Cellular respiration is more efficient to make ATP. It can make 38 ATP.

Question 2

Where in the cell does each occur?

Answer 2

Aerobic:
Glycolysis - cytoplasm (glucose molecules broken down into pyruvate)
Citric Acid Cycle (Krebs cycle) - mitochondria (pyruvate broken down into carbon dioxide)
Electron Transport Chain - mitochondria (used to produce ATP)
Anaerobic:
Lactic Acid Fermentation - cytoplasm (pyruvate converted into lactic acid)
Alcoholic Fermentation - cytoplasm (pyruvate turns into ethanol and carbon dioxide)

Question 3

What does the term aerobic mean? What does the term anaerobic mean?

Answer 3

Aerobic means with the use of oxygen and anaerobic means without the use of oxygen.

Question 4

What are the two types of fermentation called and how do the products differ?

Answer 4

Lactic Acid Fermentation - pyruvate is converted into lactic acid
Alcoholic Fermentation - pyruvate is converted into ethanol and carbon dioxide

Question 5

Which organisms can perform the different types of fermentation?

Answer 5

Lactic acid Fermentation - Muscle cells
Alcoholic Acid Fermentation - Yeast
