How Enzymes Are Biological Catalysts

By definition an enzyme are biological catalyst that facilitates specific chemical reactions. What this means is that an enzyme is a protein its function is to function as catalyst which lowers the activation energy for the reaction to occur quicker. Enzymes have different ways that it reacts with substrates. One way is that an enzyme reacts with a substrate is by bringing two substrates together correctly or by stressing particular bonds of substrates. By doing on or the other an enzyme can lower the activation energy of the reaction. More specifically the substrate has to attach to the enzymes active site for the catalyst to occur. For the substrates to attach to these active sites they have to match the size of the active site or else they …show more content…
There is a point in where if the temperature is increased to high instead of lowering the activation energy it starts to denature the enzyme; this point is called the optimum temperature. pH also has an optimum level in which the enzymes can perform optimally. The pH levels depends on the hydrogen ion concentration that the enzyme is dissolved in; the optimum pH level for an enzyme is 6 to 8 but, there are some enzymes that can thrive in different pH levels. The enzymes that reside in the stomach have a usual pH level of 2. Enzyme concentration is basically the amount of enzymes are in the reaction. As the enzyme concentration increases it will increase the rate at which the product can be produced. This will happen because when the enzyme concentration is increased the substrates will have more active sites to bind to causing more reaction to be performed. There is a limit of how much enzymes can before the amount of enzyme in the reaction staggers the amount of products being made. When the concentration is too high the amount of substrates will get used which will then lower the rate of the
