Question

In biological systems, there are several membrane transport systems responsible for the passage of ions, such as na or k , or small molecules, such as glucose or amino acids, through biological membranes.

Answer 1

different types of ions channels are present on the neural membrane .the axonal memberane is more permiable for potassium ions and nearly impermeable for Na ions .and the resting plasma membrane is a permiable membrane for the passage of k and Na ions..
