What are the different ways in which glucose is oxidised to provideenergy in various organisms? |
|
Answer» Aerobic respiration: Glucose is completely oxidised to carbon dioxide and water in the presence of oxygen, with the release of a considerable amount of energy. This type of oxidation occurs in most of the living organisms such as human beings, birds, snakes, frogs, fish, etc. The first step is breakdown of glucose -a six carbon molecule to pyruvate- a three carbon molecule.This can be done in three cases. The first is aerobic respiration(takes place in presence of oxygen) The second is anaerobic respiration(takes place in absence of oxygen) and the next pathway takes place in lack of oxygen. |
