Cells require oxygen for aerobic respiration, which produces carbon dioxide; both gases move between cells and the environment via diffusion.
Por que as células precisam de oxigênio e como elas se livram do dióxido de carbono? Elas precisam de oxigênio para a respiração aeróbica, que produz dióxido de carbono. Ambos os gases se movem entre as células e o ambiente através da difusão.
