Water
Water is the substance that plays a major role in most of the chemical reactions that occur in living cell.
Water is a clear, tasteless, and odourless substance that is found in high amounts in living organisms, and is required by all forms of life. Water plays a major role in most of the chemical reactions that occur in living cells. Water is present both within and outside cells, and almost all chemical reactions take place in water solution. Water also acts as metabolite in many chemical reactions. It is either a reactant or a product of reaction. Water is involved in chemical processes such as digestion, photosynthesis, and aerobic respiration.
Answer:
the alveoli are made of thin squamous (type I) alveolar cells which allows for the quick diffusion carbon dioxide and oxygen.
Explanation:
Diffusion of gases takes place between the alveolar cavity and the blood in the capillaries. Oxygen being more concentrated in the alveoli diffuses across the epithelium of the alveoli and the endothelium of the capillaries into the blood. The epithelial walls of the alveoli are moist and thin thus enhancing the diffusion.
