Difference between aerobic and inanaerobic respiration and name some organisms that use the anaerobic mode of nutrition
Answers
Both aerobic and anaerobic respiration involve chemical reactions which take place in the cell to produce energy, which is needed for active processes.
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).
Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen. This is useful in tissues which have a high energy demand such as in working muscles, in which there is not enough oxygen to produce all the energy needed by using aerobic respiration alone. Anaerobic respiration takes place in the cell cytoplasm and produces lactic acid. The chemical equation is C6H12O6 -> 2C3H6O3 (Glucose -> Lactic acid). The lactic acid then needs to be oxidised later to carbon dioxide and water afterwards to prevent it building up. This process requires oxygen and therefore following anaerobic respiration there is oxygen debt in the cell, as oxygen is needed to break down the lactic acid produced.
Organisms which are anaerobic are yeast and bacteria etc
Explanation:
Cellular respiration is a process that takes place inside the cells, where the breakdown of glucose molecules releases energy. The process can be conveniently divided into two categories based on oxygen usage, namely aerobic and anaerobic respiration.
Differences between aerobic and anaerobic respiration
The difference between aerobic and anaerobic respiration is tabulated below.
Aerobic Respiration Anaerobic Respiration
It is the process of cellular respiration that takes place in the presence of oxygen gas. It is the process of cellular respiration that takes place in the absence of oxygen gas.
It involves the exchange of gases between the organism and the outside environment. Exchange of gases is absent.
It can be found in the cytoplasm and the mitochondria It can be found only in the cytoplasm.
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide, and energy
All higher organisms such as mammals have this type of respiration. Lower organisms such as bacteria and yeast use this type.
