What are the two types of
Respiration?
O-levels: Grade 9,10 and 11
Do you know how our body gets energy? Our body gets energy through the process of
respiration
...


What is Respiration?
Respiration is the breakdown of food molecules which releases energy in our body
cells
...


There are two types of respiration:
● Aerobic Respiration
● Anaerobic Respiration
Aerobic Respiration:Aerobic respiration is the oxidation of food substances in the presence of oxygen
to produce carbon dioxide, water and large amounts of energy
...
Glucose in the reactants is obtained from the food one eats
...
Mitochondria contains these enzymes and play a very
important role in aerobic respiration
...
Organisms like trees and
humans require more energy so they respire aerobically
...

Anaerobic Respiration:It is the breakdown of food molecules in the absence of oxygen to produce small
amounts of energy, carbon dioxide and ethanol
...

Mainly micro-organisms respire anaerobically that live in areas where less amount of
oxygen is present
...
However, yeast cannot be very active when it
undergoes anaerobic respiration or alcoholic fermentation
...

Anaerobic respiration in Muscle cells:
During vigorous exercise, when your body requires more oxygen, our muscles respire
anaerobically to repay the oxygen debt
...

Here is the word equation for anaerobic respiration in human:
Glucose____ lactic acid+ small amount of energy
