Cell Bio - Fermentation Flashcards
1
Q
What is fermentation?
A
Break down of glucose to produce substances that can be used to make chemical energy. It occurs in the ABSENCE of oxygen
ENZYME CONTROLLED
2
Q
How much ATP does fermentation produce?
A
2 molecules
3
Q
- Describe the Fermentation pathway in ANIMAL cells
- Provide an equation
A
- Glucose is broken down into 2 pyruvate molecules
- Pyruvate is converted to lactate/lactic acid
- glucose ⇌ lactate + energy
4
Q
- Describe the Fermentation pathway in Plant cells
- Provide an equation
A
- Glucose is broken down into 2 pyruvate molecules
- Pyruvate is converted to carbon dioxide and ethanol
- glucose → carbon dioxide + ethanol + energy
(irreversible as CO₂ diffuses away)
