Why PH Affect Enzyme Activity?
The rate of a chemical reaction and/or the enzyme activity is greatly influenced by the structure of the enzyme. Or in other words, a change in the structure of the enzyme affects the rate of reaction. When pH of a particular medium changes, it leads to alteration in the shape of the enzyme. No only on enzymes, the pH level may also affect the charge properties and shape of the substrate. Within a narrow pH range, changes in the structural shapes of the enzymes and substrates may be reversible. But for a significant change in pH levels, the enzyme and the substrate may undergo denaturation. In such cases, they cannot identify each other. Consequently, there will be no reaction as such. This the reason why, pH affect enzyme activity. How does PH Affect Enzymes? Speaking about the connection between pH and enzymes and/or pH effect on enzymes, each and every enzyme is characterized by an optimum pH. At this specific pH level, a particular enzyme catalyzes the reaction at the fastest rate
