What are the different ways in which glucose is oxidised to provide energy in various organisms? Give one example of each.


Glucose is oxidized, to provide energy in various organisms, in two ways –

i. Aerobic respiration – this respiration process takes place using oxygen. For example, plants and animals oxidize glucose and break it down into carbon dioxide and water to release energy.


ii. Anaerobic respiration – This respiration process takes place in the absence of oxygen. For example, yeast and some bacteria oxidize glucose into ethanol and carbon dioxide.
