How Does the Plasma Membrane Contribute to Cellular Protection?
The plasma membrane plays a vital role in maintaining cellular integrity and homeostasis. It acts as a selective barrier, regulating the entry and exit of ions, nutrients, and waste products. The selective permeability of the plasma membrane is essential for protecting cells against toxic substances. Specific transport proteins and channels embedded in the membrane facilitate the controlled movement of substances, thereby preventing the accumulation of toxic compounds within the cell.
