The answer is potassium and sodium ions. In a state of rest, both inside and outside the cell membrane are potassium and sodium ions, but with different concentrations. The concentration of potassium ions (K +) on the inside of the membrane is about 35 times higher than the concentration on the outside. In contrast, the concentration of sodium ions (Na +) on the outside of the cell membrane is about 10 times higher than the concentration on the inside. The differences in ion concentrations on the inside and outside of the membrane encourage the diffusion of these ions through the cell membrane.
<h2>Further Explanation
</h2>
In a state of rest, between the inner and outer sides of the cell membrane, there is a potential difference called the cell resting potential. This potential is negative on the inside and positive on the outside of the cell membrane. The following will describe how the cell resting potential occurs.
Potassium is one of the mineral content in the body. Potassium or often called potassium is a very important function for the body. Low potassium levels have major consequences for bodily functions.
Potassium deficiency affects overall health. This mineral is very important for the functioning of muscles, including the heart.
About 98% of the potassium in the body is inside cells and every small change in its level can have a serious impact on nerves, muscles, and heart. The kidney is the main organ that controls the balance of potassium, by removing excess potassium into the urine. When potassium levels are low, the body can become weak and metabolic processes can be disrupted.
Sodium is a chemical element. It has a very reactive nature, so it is not found free. sodium is very important for human nutrition, but sodium reacts spontaneously (reactive) in water, so don't eat pure sodium!
The need for sodium in the body will be fulfilled, one of them from salt consumption, where sodium and chlorine ions in NaCl will be separated from each other.
Sodium in the body functions to carry on nerve impulses and every cell in the body is needed. The balance between sodium and other ions to regulate pressure on cells and also related to blood pressure.
