The Effect of Temperature on Enzyme ActivityAbstractThis biology experiment was conducted in order to see if the change in environmental factors had any effect on enzyme activity. I tested the effects of the environment of enzymes by comparing three different temperatures' affects on milk and its glucose levels. The end result proved that environmental factors such as temperature do in fact have an affect on enzyme activity.IntroductionAn enzyme is a protein that acts as a catalyst; a substance that speeds up a reaction. Each enzyme is specific meaning that if the enzyme fails to bind at the active site with the substrate, the reaction does not take place. Enzymes are affected by environmental factors such as temperature, pH, and salinity, each dependent on their individual makeup. I will be testing the affect of varying temperature on glucose level within milk in order to test this for myself. Temperature is a measure of molecular motion. Therefore it would reasonable to conclude that an increase in the temperature would increase the molecular motion in an enzyme, and on the other hand, a decrease in the temperature would decrease the molecular motion. My hypothesis is that this will be true only within a certain temperature range. Since enzymes are selectively specific for the substance which it reacts wit, it also has a specific temperature at which it is most effective. If an enzyme is heated too much, it will denature and cause it not to be able to react. At the same time if an enzyme is chilled to a temperature to low, it will not react either.Materials*6 test tubes*test tube holder*Thermometer*hot plate*ice*2 200mL beakers*distilled water*milk*4 glucose test strips*lactaid pill*weigh paper*boiling chipsMethods1.Fill 3 test tubes with 3mL of milk. Fill 3 more test tubes with 2mL of distilled water.2.Test a sample of milk with a glucose test strip. Wait 1 minute then compare the color to the test strip bottle.3.Crush a lactaid pill in a piece of weigh paper. Separate into 3 lines. Pour 1/3 of the pill into each of the 3 test tubes containing distilled water.4.Place one test tube of milk and one test tube of the water/lactaid pill into a beaker of ice (13°C). Let the tubes chill of 3 minutes.5.Now mix the chilled tubes of water/lactaid pill and milk into one of the test tubes. Make sure they are mixed well.

However optimum activity of enzyme is at about 37ºC this is as I had expected.Overall, due to reliable repeats and in general predictions being confirmed I feel my results are reliable enough to make a conclusion. One of the main ways of improving this investigation is to change the method. I measure the volume of oxygen that was produced. In order to get pure oxygen without any other gases that are in the air I would use the same equipment but make sure that the gap between the rubber bung and solution was free from any other gases.

651 words - 3 pages helping the substrates to bind together. It is easier for substrates to react if they are closer together, thus bringing on the transition state. The second way is by repositioning them. Substrates do not travel in a particular direction and so if they are repositioned so that they collide, they will react. Another way to cause reactions is using an induced-fit model. This means that the enzyme changes its shape to better fit the substrate and make
