What factors affect enzyme activity?

The temperature, substrate concentrations and pH are three factors that can affect enzymatic activity. Enzymes are catalysts, substances that increase the rate of reactions. Without them, many necessary processes such as digestion would appear too slowly to continue life. Many enzymes have optimal temperature and optimal pH. The optimum temperature and optimal pH of the enzyme is the temperature and pH range, in which the enzyme can work best without becoming inactive or denatured, a phenomenon that occurs when proteins begin to decay.

is one of the main conditions that can affect the activity of the enzyme is the temperature. As the heat increases, molecules usually begin to move faster and faster, and this increased activity means that molecules are more likely to collide with the enzyme. The higher collision rate allows you to increase the speed of the reaction, but up to a certain point. If the temperature increases too much, the protein of the enzyme can begin to denature, the potential of the permanent process. Optimal temperature for mThe enzymes fall within the temperature range of 77-104 ° F (25-40 ° C), but some enzymes, such as those found in animals living in cold sea water or hot springs, may have a higher or lower optimum temperature to allow them to successfully perform their work.

The temperature is not the only factor that can affect enzymatic activity. If the enzyme concentration remains the same, the increased concentration of substrate, which is the molecules involved in the reaction, also affect how quickly the enzyme works. As the concentration of the substrate increases, the speed of the reaction originally increases because there is more than enough enzymes to facilitate the reaction. However, after some point, adding more substrate does not affect enzymatic activity because there are only so many enzymes available. Instead, the reaction rate will be constant, as another substrate has to wait for the available enzymes easier.

The level of pH of the solution may also affect enzymatic activity. Many enzymes can only work in a narrow pH range. If the enzyme finds itself in the enemy PH range, it could become denatured. The optimal pH for many enzymes is 7.0-7.5, but it is not always the case. Some enzymes, such as some in the human stomach, work best in a sour pH of 1.5, while others, such as some found in the intestine, work best with more alkaline pH 8.0.
