Inorganic ions, which are of no small importance for ensuring the vital processes of the cell, are represented by cations (K +, Na +, Ca2 +, Mg2 +, NH) and anions (Cl-, HPO, Н2РО, НСО, NO, PO, СО) of mineral salts. The concentration of cations and anions in the cell and in its environment is different. As a result, a potential difference is formed between the contents of the cell and its environment, providing such important processes as irritability and transmission of excitation through the nerve or muscle.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
