Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. ... An example of such a substance is lysozyme, an enzyme present in tears that destroys the cell membranes of certain bacteria.
Phosphate buffer is a buffer used in many types of reactions with the function to maintain constant pH value.
This is important because enzymes’ activity is affected by changes in pH. There is an optimum pH for every enzyme that can be defined as most favorable pH value or the point where the enzyme is most active. Phosphate buffer is often use in the measurement of enzyme’s activity because it is isotonic and non-toxic to most cells.
