The substance that can be added to the reaction mixture to maintain a high activity of the enzyme, with the reason for the same.
The acidic or basic character is expressed in terms of pH (potential of hydrogen). It is a negative logarithm of the concentration of . A solution is neutral if its pH is 7, basic if it is greater than 7, and acidic if it is less than 7. The maintenance of pH is critical to living organisms because changes in pH bring about changes in the ionic states of biomolecules.
