Question

Differentiate breathing and respiration.

Answer 1

Hint: Both breathing and respiration are different processes of living organisms. The process of taking air into and out of lungs is called breathing.
Respiration may be defined as the oxygen movement from the outside environment to the cells and carbon dioxide movement in the opposite direction. Cellular respiration is the biochemical process of releasing energy.

Complete step by step answer:

Breathing There is no requirement of enzymes in this process.It is the process of inhaling oxygen and exhaling carbon dioxide.It occurs in the lungs, nose, mouth and pharynx.Breathing is both a voluntary and involuntary process.It is involuntary during sleep and voluntary when we sing, speak, swim etc.No energy production in this process.It is called the extracellular process which takes place between the external environment and organism.

Respiration Large numbers of enzymes are required.Cellular respiration is the process of breaking down glucose to give energy, that is further used by cells to carry the cellular function.It occurs in cell organelles which includes mitochondria etc.Respiration is an involuntary and chemical process.Energy production takes place which is released in the form of ATP.It is called an intracellular process as it takes place inside the cells.

Note: Cellular respiration is the biochemical process that releases energy which is further used by body cells to perform various things such as sitting, running, walking and many other activities.
