One electric scale 0. Since some beakers will not have very significant reactions as stated in hypothesisI recorded the state of the state of each beaker of jello at two minutes after the independent variable have been put in, while also noting any specific changes in each beaker.
Free Essays Tags Background Information: Trying is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment.
That as pH Increases. He rate of enzymatic activity Increases until the optimum pH Is reached. To Investigate the effects of different pH levels on reactions catalysts by the enzyme trying.
Trying solution, Noah solution and HCI solution The solutions are irritant to the skin and can be lethal is consumed. It can also be harmful if contacted with eyes. Wear safety goggles during use of solutions, if splashed onto skin, Immediately rinse with cold water.
Cuts from glass Cuts to skin when breakage occurs Immediately inform teacher and follow instructions to clear away glass Burns from heat Burns to skin from hot water, hot milk or Bunsen flame Immediately hold under cold water and inform teacher Variables: Whether protein disappears digestion Controlled Pepsin, egg white.
Experimental Control Test tube with water Method: Collect 4 test tubes and label them from A to D. Add about mm of egg white into each test tube. Add 3 drops into test tubes A, B and C. Add 10 ml Hydroxide into test tube C resulting as a basic pH test. Heat the test tubes in a water bath until they all reach approximately ICC.
Remove the test tubes from the heat after 10 minutes and record any observations in a table. Repeat the experiment 10 times with the aim of achieving consistent results, this will increase the reliability of the experiment.
A control experiment must be performed. Why is it performed and what did yours show? A control experiment must be performed so you can observe the effects of your test and how variables can alter results. Mine showed that as pH levels increase, the enzymatic activity increases, this is shown by the control which had no effect as opposed to the one with an acidic pH which gave the desired results which was that digestion had occurred as a result of an increased PH.
What variables did you control and how did you do it? I controlled the pepsin by using it in all different pH level tests except for the control. This was done to see whether the absence of the enzyme had an effect on the substrate. If you were to repeat your experiment how and why would you do things differently?
I would have repeated the experiment however, I would have had a control for each of the different pH levels to observe the effects of the enzyme.For simple enzyme assays, like some proteases, only the enzyme and the substrate in a buffered solution are needed.
But most assays require various components, two to three substrates, cofactors, activators, and reagents for stabilization or prevention from deactivating processes, like oxidation or proteolysis. Most enzymes are protein molecules, which increase the reaction rate and function best under optimal conditions or temperatures related to the environment and the host organism where the enzyme is found.
