Optimal Temp and PH of Enzymes

The first thing that you should learn about enzymes is that they are those proteins that are responsible for speeding up the rates of different reactions in all living cells. It’s true that these catalysts are produced by cells in a small amount that is not consumed during chemical reactions. Basically, they are responsible for reducing the requirement of activating energy to start reactions.

Keep in mind that enzymes are quite specific so that they may require certain coenzymes to carry out the necessary activity. For example, they consume food substances and break them down in cells to provide the energy necessary for efficient respiration. You may have heard about such important enzymes as proteases, lipases, and carbs.

Each enzyme shows its maximal activity when it has its optimum pH. The activity of enzymes is slow both below and above this level, and they also may have active sites where substrates bind. They are called damaged because their shape is changed by not optimum pH levels. This means that substrates can’t fit active sites any longer so that the necessary reaction doesn’t happen. Take into account that the optimal pH of enzymes is 7, and when it moves further, their activity starts slowing down gradually.

Besides, all enzymes show their highest activity at an optimum temperature so that the rate of reactions both below and above this level is slower. When increasing temperature levels, you will end up with the increased frequency of collisions because molecules start moving faster and faster. Remember that the activity of enzymes doubles until their reach an optimum temperature for each ten degrees. However, increasing it further will only damage their active sites and change shapes so that substrates will no longer fit them. Another important aspect that should be remembered is that enzymes are totally denatured at temperature levels that are higher than 60 degrees.

In conclusion, it’s obvious that temperature and pH affect the activities of all enzymes to a great extent. They are quite sensitive to pH and temperature levels so that they must be considered in any chemical reaction that involves these substances. You should understand how to determine these requirements to avoid common mistakes. There is another factor that may affect their activity, and it’s all about a substrate concentration so that you need to consider it too to get the most of your specific chemical reactions.
