What is the significance of the na and k relationship in cellular biology?

The relationship between sodium (Na) and potassium (K) in cellular Biology is significant because they are essential for maintaining the balance of ions inside and outside of cells. This balance is crucial for various cellular functions, including nerve signal transmission, muscle contraction, and maintaining cell volume. The Na-K pump, a protein found in cell membranes, actively transports Na out of the cell and K into the cell, helping to establish and maintain this ion balance.
