The reaction rate of an enzyme -catalyzed reaction is increased by the increase of substrate concentration. The number of molecules formed per minute increased as the amount of substrate increased. The relationship isnt linear because the amount of product didnt increase by the same amount between the amount of concentrations of substrate. As the substrate concentraion increases the initial reaction rate continues to increase until a certain point where it reamains the same no matter how many more substrates are added. The highest rate of reaction was 4g of substrate resulting with 8g of substrate producing the same result.

The maximum initial reaction rate for this enzyme at pH7 is 350 molecules of products formed per minute at 4g and 8g of substrate concentration.

The maximum initial reaction rate cannot be reached at low substrate concentrations because in order to create the product substrates are used through products. More substrates equal more products. The reaction, according to the table and graph, increased as the concentration of the substrate increased. Less substrates cause for lower reaction rates.

My data indicates about the optimum pH level for this enzyme catalyzed reaction is 7. At the level, pH7, the reaction rate is at the highest compared to other levels. After or before 7 the reaction rate decreases.

The importance of temperature-regulating mechanisms in organisms is very important because if our bodies could not regulate their temperatures some of the reactions needed to happen would not occur. Our body temperature would be too high or too low. We would not be able to function in the correct manner.
