Question

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

Answer 1

There are two ways in which glucose is oxidized to provide energy in various organisms: 

(i) Anaerobic respiration: The respiration which takes place without oxygen is called anaerobic respiration.Example: Yeast and some bacteria break down glucose into ethanol and carbon dioxide. 

(ii) Aerobic respiration: The respiration which uses oxygen is called aerobic respiration.Example: Plants and animals break down glucose completely into carbon dioxide and water to release energy.
