Effect Of Temperature On Amylase Activity Coursework

When the water baths were at a temperature of 20c and 40c, the enzymes worked at almost exactly the same rate and both reactions finished at 3 minutes and 30 seconds. This would help further the investigation as this variable inside the body is very important. The enzymes are not changed in the reaction which they take part in, therefore they can be used over and over again.

Introduction an enzyme is a protein that acts as a catalyst a substance that speeds up a reaction. We investigated the effects from four different parameters (substrate concentration, ph level,. Enzymes are biological catalysts that speed up chemical reactions, without being used up or changed.

The only variable which i hope to change is the temperature. I stuck to the method, which i had planned, and the results from using this method, were as accurate as possible. A line of best fit was more appropriate for my graph of results, as it gave a smooth curve.

The functions of enzymes vary because of the enzymes structure. A group of birds that he saw reminded him of. It is a laboratory essay on an experiment we did over enzymes and the effects of the parameters on enzymes.

Other experiments that could be carried out to extend this work and provide me with more evidence is the affect of concentration of the enzyme and starch. ). Amylase is a carbohydrase, which converts starch to simple sugars in the salivary glands.

At 0c the enzymes worked, although fairly slowly, due to the fact that they lacked energy and therefore, did not collide with the substrates as often. I cannot even describe how much course hero helped me this summer. Increasing the amount of temperatures that the solution of starch and amylase were tested at this would allow the experiment to become more accurate and also the optimum temperature would become more accurate as well as the temperature at which the enzymes are destroyed. Using a different enzyme and substrate would also make the experiment more accurate as it would verify that these results do not just happen with amylase and starch, but also with other enzymes and substrates that also work in our bodies. To investigate the effect that temperature has on enzyme activity i am going to use the enzyme amylase, which is used as a biological catalyst to break down starch, which cannot pass through the gut wall due to the size of the molecules, into smaller ones.

    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. The results which we collected were as accurate as possible because to make it a fair test, we tried to keep each separate experiment the same and also used the minimum time in between each reading. The clock should be started as soon as the amylase is added and after the first 30 seconds, using the pipette a drop of the solution is added to the iodine in the spotting tray. Test each separate temperature more than twice this is to prove that each temperature is affecting the enzymes the same way each time and that the previous result was not a fluke. The enzymes are not changed in the reaction which they take part in, therefore they can be used over and over again.

    The only variable which i hope to change is the temperature. This is the right temperature for the random movement of molecules, so that they collide as often as possible, without being destroyed. Other experiments that could be carried out to extend this work and provide me with more evidence is the affect of concentration of the enzyme and starch. By using my experiment plan, i hope to obtain the most accurate results possible. We investigated the effects from four different parameters (substrate concentration, ph level,.
