Cellular
respiration involves a series of chemical reactions. The enzymes
increase the rate of the reactions. The reactions that are catalysed by
enzymes actually helps the organism to grow, respond to various changes
in the environment, reproduce and continue maintaining their own
structures. Cellular respiration is also considered a part of the
metabolism process. This process actually helps in carrying the oxygen
through the blood.
Two types: Anaerobic and aerobic respiration
Anaerobic respiration doesn't use oxygen during its respiration process while the aerobic respiration uses oxygen.
