What are the different ways in which glucose is oxidised to provide energy in various organisms?
There are two different ways in which glucose breaks down to provide energy in the various organisms. Glucose or carbohydrate present in the organisms in the form of food and they oxidize to give energy to the organism. Large glucose molecule breaks down into the smaller ones as seen in the aerobic and the anaerobic processes. Two ways are following- aerobic and anaerobic respiration.
-
Aerobic respiration: Glucose get break down into the carbon dioxide, water and energy is released in the form of ATP. It yields more energy available in glucose. It occurs in the mitochondrial matrix and release more energy than anaerobic respiration.
C6H12O2 + 6O2 → 6CO2 + 6H2O + Energy
(Glucose) (Oxygen) (Carbon dioxide) (Water) (Stored in ATP)
-
Anaerobic respiration: Lower organisms like bacteria and yeast have this type of respiration. In bacteria, glucose breaks down into lactic acid and energy without the use of oxygen and without the production of carbon dioxide. It occurs in the cytoplasm and releases less energy.
C6H12O6 → 2CH3CHOHCOOH + Energy
(Glucose) (Lactic acid)
