Define breathing. State the differences between breathing and respiration. |
| Answer» \tBreathingCellular RespirationBreathing involves the process of inhaling oxygen and exhaling carbon dioxideCellular respiration is the process of breaking down of glucose to produce energy, which is then used by cells to carry out the cellular function.Breathing takes place in the lungs. Also involves the nose, mouth and pharynxRespiration takes place in cellsBreathing is voluntary as well as an involuntary physical process. (For example, breathing during sleep is involuntary. Voluntary breathing is observed when we sing, speak, swim or for relaxation techniques)Respiration is an involuntary chemical process.There is no production of energy in this process.Energy is produced and released in the form of ATP.As it occurs outside cells, it is called the extracellular process. (Occurs between the organism and the external environment)As it occurs inside cells, it is called the intracellular process.No enzymes are used during the process.A large number of enzymes are used during the process.Breathing occurs through respiratory organs, including the nose, lungs, etc.Respiration takes place in cells and cell organelles, including mitochondria, etc.\t | |
