Anaerobic Respiration

Question 1

What is anaerobic respiration (respiration)?

Answer 1

It releases energy from the breakdown of glucose without oxygen, producing lactic acid in animals and ethanol and carbon dioxide in plants and microorganisms.

Question 2

Anaerobic respiration uses oxygen. True or false?

Answer 2

False

Question 3

When does anaerobic respiration occur?

Answer 3

It happens due to:
•Not enough oxygen
•Intense exercise
•It provides extra energy for short periods of time

Question 4

Why does it cause cramps?

Answer 4

Build up of lactic acid produced in anaerobic respiration can cause cramps in your muscles.

Question 5

What is oxygen debt?

Answer 5

Oxygen debt is the amount of extra oxygen the body needs to replace after intense exercise in order to break down lactic acid .

Question 6

Where does anaerobic respiration occur ?

Answer 6

The cytoplasm of cells

Question 7

Anaerobic respiration produces energy faster than aerobic respiration. True or false?

Answer 7

True

Question 8

What are the reactants of anaerobic respiration?

Answer 8

Glucose

Question 9

What part of respiration is absent during anaerobic respiration?

○ Carbon dioxide
○ Ethanol
○ Oxygen
○ Pyruvate

Answer 9

Oxygen

Question 10

What does anaerobic respiration in some microorganisms produce?

Answer 10

Ethanol and carbon dioxide instead of lactic acid. This process is called fermentation.
