What are different types of cellular breathing?
cell breathing is a process by which cells convert different forms of chemical energy to adenosine triphosphate or ATP, a molecule that is used to "transport" usable cellular energy. Cell breathing may proceed with different mechanisms based on the cellular conditions during the breathing process. For example, oxygen is the main factor - breathing takes place in various mechanisms in aerobic conditions or conditions in which oxygen is present than in anaerobic conditions or conditions in which oxygen is not present. Some organisms are able to switch between aerobic and anaerobic methods of breathing based on environmental conditions, although in such cases anaerobic breathing is not generally sustainable for a long time.
Aerobic breathing is a cell breathing that requires oxygen. People and many other organisms use this form of breathing because chemical properties of oxygen allow very effective energy. Oxygen for aerobic cell breathing is provided by breathingm; If oxygen intake is insufficient to ensure sufficient oxygen, short -term anaerobic mechanisms must be used to replenish aerobic mechanisms.
The raw materials used during the respiratory processes of energy transmission are provided by food consumption that is divided into a chemical form that can be used during the responses that occur during breathing. It should be noted that cell breathing itself requires energy because some ATP is used to make more.
In some cases, aerobic cell breathing is not enough to ensure all the energy needed for the cellular needs of the body. This is common when a person deals with athletic practices that strongly tax muscles. Aerobic mechanisms are unable to keep up with energy needs, so the process referred to as fermentation is activated to complement energy production. This process is much lessEffective than its aerobic counterpart and produces only two ATP molecules on used glucose molecules compared to 38 produced through aerobic mechanisms. It also creates a large amount of energy -rich waste that cannot be divided into a usable form.
Some organisms live in anaerobic conditions and therefore have cellular respiratory processes that do not include oxygen. Some of these organisms actually die in the presence of oxygen; Such organisms are referred to as mandatory anaerobes. Most organisms that primarily use cellular breathing mechanisms are small and unfulfilled and tend to lack energy needs such as muscle movement and complex digestive processes.
