|Basis for Comparison
||The term Breathing is defined as a biophysical process in which inhalation and exhalation are used to exchange gases.
||The term Respiration means a biochemical process which is used to release energy from the organic compounds that are then used to carry out various physical activities.
||Inhalation and exhalation are two steps in Breathing.
||There are three steps in respiration: glycolysis, Kerb's cycle and electron transport chain.
|Voluntary or Involuntary
||Breathing involves voluntary actions as well as involuntary ones.
||Respiration involves involuntary action.
||Breathing is a biophysical process.
||Respiration is a biochemical process.
||Breathing does not involve any metabolic reactions.
||Respiration is a multi-reaction metabolic process.
||Breathing involves various respiratory muscles and the diaphragm.
||During respiration, muscles are not involved.
||Gas exchange and ventilation are the two main activities during breathing.
||Gas exchange and breakdown into simpler forms are the two main activities during respiration.
||The diaphragm and respiratory muscles regulate breathing.
||Respiration is regulated by different enzymes.
|Intracellular or extracellular
||Breathing is an extracellular process.
||Respiration is an intracellular process.
||The breathing includes most of the respiratory system's organs.
||Respiration occurs in the mitochondria of cells.
||Enzymes are not involved in breathing.
||Various enzymes catalyze different respiration steps.
||Breathing does not provide energy.
||Respiration produces energy.
||In all vertebrates and some arthropods, breathing occurs.
||In all living organisms present on the earth, respiration occurs.
||Breathing gives oxygen to various parts of the body.
||Respiration produces large amounts of energy from the degradation of organic compounds.
