ionivirtauksen
Ionivirtaus, also known as ionic current, refers to the flow of ions through a biological membrane or an artificial membrane, driven by an electrochemical gradient. This process is fundamental to various biological functions, including nerve impulse transmission, muscle contraction, and cellular communication. Ionivirtaus can be categorized into two main types: passive and active.
Passive ionivirtaus occurs when ions move down their electrochemical gradient, without the need for energy expenditure.
Active ionivirtaus, on the other hand, requires energy input, typically in the form of ATP, to move
Ionivirtaus plays a crucial role in maintaining cellular homeostasis, generating action potentials, and regulating cellular volume.
