anaerobic respiration

Question 1

What does glycolysis involve?

Answer 1

Glycolysis and the production of pyruvate

Question 2

Where does the pyruvate not go?

Answer 2

The mitochondria

Question 3

How much ATP is produced during glycolysis?

Answer 3

2 molecules

Question 4

How is the pyruvate reduced?

Answer 4

Using reduced NAD produced during glycolysis

This enables the regeneration of NAD.

Question 5

What does the reduction of pyruvate enable?

Answer 5

The regeneration of NAD

Question 6

What does the regeneration of NAD ensure?

Answer 6

A continual supply of NAD is provided for glycolysis to continue

Question 7

What is the product of reducing pyruvate in animals?

Answer 7

Lactate

Question 8

What is the product of reducing pyruvate in plants (yeast)?

Answer 8

Ethanol and carbon dioxide

Question 9

What would happen if NAD wasn’t regenerated?

Answer 9

Glycolysis would stop as all the NAD would be reduced and there would be no NAD available to allow the oxidation of triose phosphate to pyruvate
