Similarities:

The similarities between aerobic and anaerobic respiration, is that they both use glucose as the starting molecule. This is called the substrate.
In addition, both aerobic and anaerobic respiration produce ATP, however, aerobic respiration produces a lot more ATP compared to anaerobic respiration.
Food is oxidized in both cases and energy is released.

Differences:

Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen.
Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration.
Aerobic respiration releases more energy than anaerobic respiration.

Give the name of organs use to respire in amoeba

Kritika Trehan 7 years, 9 months ago

We know that amoeba is a unicellular organism which lives in fresh water. This organism does not have a specialized organ to do the process of respiration. So in amoeba respiration takes place through its cell membrane also called plasma membrane. Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion. The oxygen gas diffused inside the body is used up by amoeba. In the body the oxygen gas absorbed is used to break down the complex food material into simple molecules. During these metabolic reactions in the body of amoeba the oxygen gas is converted into carbon dioxide gas. The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.
