Question

Differentiate between aerobic respiration and anaerobic respiration.

Answer 1

Respiration can be of two types:

• Aerobic respiration (respiration that takes place in presence of oxygen)
• Anaerobic respiration (respiration that takes place in absence of oxygen)

Difference between them:

Aerobic Respiration	Anaerobic Respiration
Aerobic respiration occurs in presence of oxygen.	Anaerobic respiration takes place in absence of oxygen.
Both glycolysis and krebs cycle takes place in this type of respiration.	Only glycolysis occurs in this type of respiration.
It provides more energy i.e. 38 ATP molecules	It provides less energy i.e. 2 ATP molecules.
The end products are CO2 and H2O.	The end products are either ethyl alcohol or lactic acid and CO2.
