Enzymes Objectives Measure the effects of changes in temperature, pH, and enzyme concentration on reaction rates of an enzyme Explain how environmental factors affect the rate of enzyme-catalyzed reactions. What would happen to your cells if they made a poisonous chemical? You might think that they would die. In fact, your cells are always making poisonous chemicals.

Conclusion and Evaluation6 3. Improvements7 Design Look to sheet titled: Wear safety goggles and a lab coat to avoid getting any acid on your person, and dispose of the acids in a sink with plenty of water. Collect the used liver samples and dispose of accordingly.
Conclusion and Evaluation 3. Conclusion The experiment was meant to create an artificial catalase reaction between the enzymes in the liver sample and hydrogen peroxide. The sample in test tube 2 reacted with the hydrogen peroxide and produced oxygen bubbles at a somewhat steady pace, while the sample in test tube 3 reacted vigorously at first and then slowed down as most of the enzyme had been used up.
Random Errors The liver was quite hard to get into perfect? Also when the reaction was very rigorous, the oxygen bubbles sometimes lifted the liver out of the hydrogen peroxide, causing it to stop reacting with the hydrogen peroxide.
While not a major issue, sometimes the time at which the results were checked were not exactly at the designated 30 second intervals, due to many things going on at once.
Systematic Errors The ruler we were using was quite old and dirty, with some of the finer millimeter markings rubbed off or obscured, leading to readings that were not as accurate as they could have been. The molarity of the chemicals used can also be put into question.
Improvements The liver could be frozen or in some other way petrified to make the cutting easier and more precise. The liver should be checked constantly and adjusted back down with a glass rod if necessary. Enough time should be allocated to ensure that the experiment can be done in a calm and orderly fashion to avoid any oversights in the time taking.
Clean and clear rulers should be used to measure the bubbles. The molarity of the chemicals should be checked with titration or some other form of double checking the molarity.Catalase Lab Report As the catalase and the substrate interact, the substrate is brought into the catalase and broken apart into water and oxygen.
This process may be able to happen naturally, but the enzyme, catalase, speeds up the process. - Lab Report Discovering Which Common Nut is the Best Heat Source when Burned Purpose: To find what common nut is the best heat source when burned.
Research: In today's world, almost everything we do needs power from fossil fuels or waterfalls. This reaction occurs spontaneously without catalase, but the enzyme speeds the reaction considerably. This lab’s purpose is to prove that catalase does speed the decomposition of hydrogen peroxide and to determine the rate of this reaction.
Apr 19, · ★DIY Organic Potato Tower Experiment Final Part Grow Potatoes like you have never seen before. - Duration: Dan Rogers 65, views. Catalase activity is a function of aerobic process.
Organisms incubated anaerobically must be exposed to atmospheric oxygen for a minimum of 30 minutes before a catalase test is performed. Failure to complete this step may produce false-negative results. While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss.
