Why internal respiration is called a physico-chemical process? |
| Answer» Internal respiration\xa0is the exchange of oxygen and carbon dioxide between blood in the “systemic capillaries” and the cells via the interstitial fluid.\xa0Respiration\xa0is a\xa0chemical reaction\xa0that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other\xa0chemical processes\xa0needed for life can happen.\xa0Cellular respiration\xa0involves the conversion of food to energy. Aerobic\xa0respiration\xa0is a\xa0cellular respiration\xa0that requires oxygen while anaerobic\xa0respiration\xa0does not. | |
