Explanation:
The natural salt content concentration of the environment in which lactase normally functions is that of 2.5%.
Lactase is an enzyme. Enzymes are metabolic catalyzers, that work to greatly speed up any metabolic reactions that are specific to the enzyme. In the case of lactase, it is produced in the small intestine and will work to permit the body the ability to digest whole milk and other dairy products. Like most enzymes, it is affected by its environment and therefore by the salt concentrations.
Lactase is an enzyme that will work most optimally at l<u>ow </u><u>salt concentrations</u><u>.</u> These are the <u>natural salt contents of the body</u>, wherein optimal performance is reached at a <u>salt </u><u>concentration of </u><u>2.5%</u>. This is the peak performance for salt concentration levels, any higher than this and the enzyme will begin to denaturalize and functionality will decrease.
