Respiration is a metabolic process that regulates exchange of gasses within the cell. Through the process oxygen received by cell and react with glucose and produces carbon di oxide. Simaltaneously, carbon di oxide expells from cell and expelled to environment through lung.
From uni cellular organism to multi cellular organism produces energy as a form of ATP with the process of respiration.
Respiration could be Aerobic or Anaerobic
In Aerobic respiration oxygen is required, but in anaerobic respiration oxygen is absent.
In a respiration two process are found.
Ventilation and purfuration
Ventilation is how lung inhall oxygen and expell carbon di oxide.
Purfuration is a process by which gaseous exchange occurs within cell to blood stream.
Phase of resporation
There have three phases of respiration
Glycolysis
Oxidative phosphorylation
Krebs Cycle
