Q What is the difference between respiration meaning gas exchange and cellular respiration?
Respiration meaning gas exchange is the process in which an organism absorbs from the environment gases necessary for it's expels gases and cellular metabolism that are products of this metabolism. Cellular respiration aerobic or anaerobic is the chemical reaction in which organic molecules are degraded to make ATP molecules, the key energy source for the metabolism.
Gas exchange is fundamental for cellular respiration since the supplying of some reagents oxygen, in aerobic cellular respiration and the expelling of some products for example carbon dioxide of this chemical reaction depends on gas exchange.
