How Does Temperature Affect the Enzyme Activity?

Temperature plays an important role in regulating the response in biology. As the temperature increases, the enzyme activity increases, which in turn increases the reaction rate. This also means that activity is reduced at cooler temperatures. All enzymes have a certain temperature range when they are active, but they work best at certain temperatures. Whether they are industrial enzymes, enzymes for daily use or other enzymes. What is an enzyme?rnAn enzyme is a protein that acts as a catalyst in a biochemical reaction, and it can increase the reaction rate without being consumed in the reaction. Thousands of enzymes work in the body of animals to achieve important functions such as digestion and energy production. Biological and chemical reactions can occur very slowly, and organisms use enzymes to bring the reaction rate to a more favorable rate. Enzymes have multiple regions that can be activated by cofactors to turn them on and off. Cofactors are usually vitamins consumed by various food sources and open the active site on the enzyme. The active site is where the enzyme reacts and can only act on one substrate, which can be other proteins or sugars. A good way to think about this is to lock and key models. Only one key can open the lock correctly. Similarly, only one enzyme can attach to the substrate and make the reaction faster. Types of enzymernYour body contains about 3,000 unique enzymes, each of which accelerates the reaction of a particular protein product. Enzymes can make your brain cells work faster and help your muscles move. They also play an important role in the digestive system, including amylases that break down sugars, proteases that break down proteins, and lipases that break down fat. All enzymes are involved in contact, so when one of the enzymes comes into contact with the correct substrate, it immediately begins to function. Temperature and enzyme reactivityrnThe collision between all molecules increases with increasing temperature. This is due to an increase in speed and kinetic energy after the temperature rises. The faster the speed, the shorter the time between collisions. This causes more molecules to reach activation energy, which increases the rate of reaction. As the molecules move faster, the collision between the enzyme and the substrate also increases. Optimum temperaturernEach enzyme has an optimal temperature, and the temperature in the human body is about 37 degrees Celsius, which is about equal to the normal body temperature of the human body. However, some enzymes work well at lower temperatures, such as 4 degrees Celsius, and some enzymes work very well at higher temperatures. For example, animals from the Arctic have enzymes that are adapted to have lower optimal temperatures, while animals in desert climates have enzymes that are adapted to higher temperatures. Although higher temperatures increase enzyme activity and reaction rate, enzymes are still proteins, and like all proteins, temperatures above 40 degrees Celsius will begin to break their activity. Therefore, the two ends of the enzyme activity range depend on what temperature the temperature starts to act on and what temperature begins to decompose the protein.
