Substances transported in plasma
WebTransport across the plasma membrane occurs unaided in simple diffusion, i.e., molecules of gases such as carbon dioxide and oxygen, as well as small molecules like ethanol, enter the cell by crossing the cell membrane without the assistance of any permease. WebThese substances include ions such as Ca 2+, Na +, K +, and Cl –; nutrients including sugars, fatty acids, and amino acids; and waste products, particularly carbon dioxide (CO 2 ), which must leave the cell. The membrane’s lipid bilayer structure provides the first level of control.
