Enzyme lab report enzyme lab report can catalase be destroyed ap biology, mod 19 the purpose of this lab was to see how catalase from different hosts reacted in different environments the optimal ph for catalase is neutral, because that it what most of the body is comprised of the optimal temperature of catalse is 986. Enzyme+catalase+lab+report catalase lab lab 2 enzyme catalysis lab report: enzymes anthony araracap period 4 ap biology enzyme action: testing catalase activity lab report background: enzymes are globular proteins responsible for most chemical activities in living organisms and act as catalysts since this is the ideal ph for the. Enzyme catalase lab report different ph activity of the enzyme catalase in breaking down hydrogen peroxide and the effect of various factors on enzyme activity introduction the enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (h2o2), which is a toxic chemical to the human body. Increasing enzyme (catalase) concentration (part a) increasing substrate (h 2 o 2) concentration (part b) c influence of ph on catalase activity a link to an introductory biology course at uncg dealing with writing a lab report writing lab reports and scientific papers:. Hypothesis: if the enzyme catalase is placed in different solutions containing different ph levels, the enzyme will function most effectively at a neutral ph, or a ph of 7 as the ph of the solutions are lowered, catalase will begin to work less effectively, and the rate of reaction will begin to decrease.
Left test tube: 5 ml of 3% hydrogen peroxide and 5 ml 05 mol/l sodium hydroxide (acting as base: ph=11) + potato slices middle test tube: 5 ml of 3% hydrogen peroxide and 5 ml water (acting as. This lab report will examine the effect temperature, concentration and ph has on enzyme activity statement of objective: three experiments with three different purposes were conducted the first experiment’s purpose was to determine how varying temperatures affect enzyme activity. The reaction rates of enzymes were very much affected by changes in temperature, ph and enzyme concentration the enzyme studied in this lab was catalase catalase breaks down hydrogen peroxide, which is toxic, into 2 safe substances- water and oxygen, by speeding up a reaction.
Biology 101 lab report: the enzyme catalase activity at different conditions more this was true because the optimum ph for the enzyme catalase is 7 ph 3 wasn’t close to the optimum ph so the reaction rate was slow, and ph10 was too high and it denatured the enzymes. In humans, catalase works only between ph 7 and ph 11 if the ph level is lower than 7 or higher than 11, the enzyme becomes denaturated and loses its structure the liver sustains a neutral ph of about 7, which creates the best environment for catalase and other enzymes. Conclusion used catalase to test two different factors: temperature and ph too low or too high of a temperature will result in a slower rate of reaction while the middle temperature (optimized temperature) will have the highest rate of reaction. Catalase lab report now that a control had been established, the next step was to test the effects of different ph in the solution our first ph that was tested was ph 4 how different concentration of enzyme catalase affects the rate of breaking down substrate hydrogen peroxide. Different enzyme concentrations, ph values, and temperatures it is possible to measure the your teacher will assign a temperature range for your lab group to test depending on your enzyme action: testing catalase activity (o 2) advanced biology with vernier 2 - 5 (o 2) table 3 time intervals (minutes.
Biology catalase lab 1 enzymes are specific different enzymes only react with certain substrates which results in the lock and key model, where the shapes enzymes and substrates match with their corresponding half catalase lab report annie chiang investigate the effect of temperature on amylase activity lanceqwerty. Lab 2: enzyme action lab 2 enzyme action—effect of enzyme concentration, temperature and ph on catalase activity prelab assignment before coming to lab, read carefully the introduction and the procedures for parts i-iii, as different concentrations of enzyme, ph values, and temperatures the rate of a chemical reaction. Next, to study the effect of concentration, three different levels of catalase are studied in the third experiment and finally, to study the effect of ph, solutions with three levels of hydrogen concentration are tested in the fourth experiment, again with hydrogen peroxide and catalase. In this catalase and hydrogen peroxide experiment, we will discover how enzymes act as catalysts by causing chemical reactions to occur more quickly within living things using a potato and hydrogen peroxide, we can observe how enzymes like catalase work to perform decomposition , or the breaking down, of other substances. Enzymes, the rate of the reaction would be far too slow to be useful an example of an important enzyme in animals is catalase, which is produced in the liver and is used to catalyze the breakdown of hydrogen peroxide (h.
If the enzyme catalase is placed in different solutions containing different ph levels, then the enzyme will function most effectively at an acidic ph or a ph of 2 how there is an optimum ph range in which the enzyme catalase works 2 see the lab report notes document about use of the word “prove” in reports. Enzyme lab report enzyme lab report 1 january 2017 metabolism figure r 3 and r 4 figure r 3 contains the recorded data of the effect of ph on enzyme reactions figure r is the graph of the recorded data it shows that the most reaction occurred at a ph of 7, this is because catalase works optimally at that ph summary this. Enzyme action: testing catalase activity lab report in this experiment, you will measure the rate of enzyme activity under various conditions, such as different concentrations of enzyme, ph values and temperatures slope ph 4 ph 7 ph 10 name date period rubric for enzyme action: testing catalase activity lab report checklist 1 2.
Hypothesis: if catalase is added to a solution of lemon juice and hydrogen peroxide with a ph of 34, then the reaction will occur at a slower rate than when catalase is added to hydrogen peroxide with a ph of 47 and at a faster rate than when catalase is added to lemon juice with a ph of 25. The most favorable ph value - the point where the enzyme is most active - is known as the optimum ph this is graphically illustrated in figure 14 extremely high or low ph values generally result in complete loss of activity for most enzymes ph is also a factor in the stability of enzymes. Recognize different enzymes and their characteristics compare and contrast the catalase in animal vs plant cells explain why temperature and ph would have an effect on enzyme activity. What affects enzyme activity lab in this section, you will determine whether or not two different organisms have catalase in their tissues part ii: the effect of extreme heat, ph & salt on catalase function in this section, you will use the potato puree to determine how heat, low ph, and high ionic concentration.
