potassium definition

The process of moving sodium and potassium ions across the cell membrance is an active transport process involving the hydrolysis of ATP to provide the necessary energy It involves an enzyme referred to as Na + /K +-ATPase This process is responsible for maintaining the large excessof Na + outside the cell and the large excess of K + ions on the inside A cycle of the transport process is potassium (K) [po-tase-um] a chemical element atomic number 19 atomic weight 39 102 (See Appendix 6 ) In combination with other minerals in the body potassium forms alkaline salts that are important in body processes and play an essential role in maintenance of the acid-base and water balance in the body All body cells especially muscle tissue
