Aerobic Respiration/Anaerobic Respiration/Fermentation

Question 1

Aerobic Respiration

Answer 1

• Aerobic Respiration happens when the body has plenty of oxygen (normally).
• Glucose+oxygen==> Carbon dioxide + water + energy
• Aerobic Respiration is more efficient, so this is preferred.

Question 2

Anaerobic Respiration

Answer 2

• Happens when the body cannot get enough oxygen. When we are running very fast or exercising, for example.
• Glucose==> lactic acid + energy
• Anaerobic respiration is less efficient, not preferred because oxygen will need to break down the lactic acid that builds up.

Question 3

Fermentation

Answer 3

Anaerobic respiration that takes place in microorganisms and plants.
Glucose ==> ethanol + carbon dioxide +(energy)
