Aerobic Respiration

Aerobic respiration include that portion of the respiratory metabolic pathway that is oxygen dependent. This also include the transition reaction. This includes the transition reactions, the Krebs cycle, and the electron transport system. All of these occur inside the mitochondria. This is molecular respiration in plant and animals.

This type of respiration needs air, and it also needs the presence of oxygen. It requires molecular oxygen. Anaerobic respiration is the catabolism of nutrients to carbon dioxide, water, and energy and involves an electron transport system in which molecular oxygen is the final electron acceptor. Most of the energy is obtained from glucose.

The overall reaction is chemically explained. Glucose or sugar (sucrose) when 'burnt' in the presence of oxygen yields carbon-di-oxide and also when reacted with water, the outcome is the release of energy as ATP. It is to be noted that glucose is oxidized to produce carbon dioxide and oxygen is reduced to produce water.

Tissue respiration is about the release of more energy, usually from the breaking up of glucose, in the tissues of all animals (land and water animals), green plants, fungi and bacteria (and other water algae’s). These living things require energy for other processes also like growth and development, movement, sensitivity, and reproduction of there body.

The most effective form of respiration is aerobic respiration: this requires oxygen or air for the process. When oxygen or air is not available, some organisms can also use anaerobic respiration .

We can respirate in both ways too. Normally we use oxygen, but when we are running in a race, we may not get enough oxygen into our blood at that point of time, so our muscles start to use anaerobic respiration to help meet the requirements of the body.
