How does carbon dioxide leave the cell

Webcarbon dioxide moves down a concentration gradient from the blood to the air in the alveoli The dissolved substances will only continue to diffuse while there is a concentration … WebCarbon dioxide (a gas) diffuses into the leaf directly through specialized mouth-shaped cells, known as guard cells. The holes made by guard cells are called stomata. Carbon dioxide and water go through a series of chemical reactions in the chloroplasts of plants to produce glucose with oxygen as a byproduct.
