Question 15

Why is fermentation reversible in animal cells

Answer 15

When oxygen is present again lactate is converted back into pyruvate

Question 16

What are the products of fermentation in plan and yeast cells

Answer 16

Ethanol + carbon dioxide

Question 17

Why is fermentation irreversible in plant cells

Answer 17

Because the carbon dioxide diffuses out the cell
