Cellular respiration in the cells of organisms is a metabolic process and metabolic reaction to
convert nutrients (specifically, biochemical nutrients) to ATP (adenosine triphosphate). This process can be
aerobic respiration (involves oxygen) or anaerobic respiration( does not
require oxygen).
Aerobic process is a cellular respiration which involves
oxygen. ATP is made when oxygen is present as it releases energy from glucose
and other carbon-based molecules. In this process, plenty of ATP molecules are
made compared to the anaerobic process which does not involve oxygen and only
creates two molecules of ATP.
