Sähkökalvo
Sähkökalvo, or the electric membrane, refers to the selective permeability barrier of a cell membrane that allows for the regulation of ion flow across the membrane. This phenomenon is fundamental to cellular physiology and plays a crucial role in various biological processes, including nerve impulse transmission, muscle contraction, and hormone secretion.
The cell membrane is composed of a phospholipid bilayer embedded with proteins, lipids, and carbohydrates. Among
The electric membrane potential arises from the unequal distribution of ions across the membrane. In resting
When stimulated, certain ion channels open, allowing ions to flow down their electrochemical gradients. For example,
