Anaerobic Respiration

Question 1

What is anaerobic respiration?

Answer 1

generating energy from glucose without presence of O2, leading to production of lactic acid

Question 2

How does anaerobic respiration differ from aerobic respiration?

Answer 2

aerobic requires O2 and produces a significantly higher amount of ATP

Question 3

Explain the process of Ethanol Fermentation

Answer 3

1. Glucose is converted into pyruvate through glycolysis.
2. Pyruvate is then converted into acetaldehyde and carbon dioxide.
3. Acetaldehyde is further reduced to ethanol, regenerating NAD+ for glycolysis to continue.

Question 4

Explain the process of Lactic Acid Fermentation

Answer 4

1. Glucose is converted into pyruvate through glycolysis.
2. Pyruvate is directly reduced to form lactate (lactic acid), regenerating NAD+ for glycolysis.
   These fermentation processes occur in the absence of oxygen to regenerate NAD+ for glycolysis to continue
