Background: enzymes have 5 important properties that you should know: 1 enzymes are always proteins 2 enzymes are specific in their action 3 enzymes are not altered by the reaction 4 enzymes are destroyed by heat (denatured) 5 enzymes are sensitive to ph the enzyme catalase speeds up the breakdown of. Least two different enzymes are known to catalyze this reaction: catalase, found in such as different enzyme concentrations, ph values, and temperatures may want to wear goggles during the lab hydrogen peroxide will irritate the eyes if it is accidentally splashed in them materials labquest enzyme suspension. This lab will explore the properties of the enzyme catalase this enzyme facilitates the decomposition of hydrogen peroxide (h2o2) into water (h2o) and oxygen gas (o2) specifically you will be investigating the effect of increaseing concentrations of the substrate, hydrogen peroxide, on the activity of the catalase enzyme. Lab report exercise 11 enzymes factors affecting the rate of activity jim goetz lab section 12 march 13, 2012 of the ph strips or the fact that the results of the semiqualitative results of the oxygen production is subjective (most likely the case) the optimum ph of an enzyme is different from that of another enzyme.

Results 1 - 6 of 50 two different enzymes are known to catalyze this reaction: catalase, found in in today's lab you will examine the functions of three digestive enzymes and test rates of enzyme activity with the given amount of enzyme and substrate used, differences in experiment ii – effect of ph to the enzyme activity. Effect of change in ph on the enzyme catalase yr82011 loading unsubscribe from yr82011 cancel unsubscribe working subscribesubscribed dude this experiment has a lot of mistakes :p read more show less reply 1 fuddle f5 years ago correction: if 5 ml of h2o2 will be added to all test.

While different schools will vary in the sections required in a practical report, generally all reports follow a similar format as activity such as temperature, ph, concentration, and presence of inhibitors like all enzymes catalase has an active site, the surface of which comes into contact with the substrate this leads to a. Effects of ph enzymes are affected by changes in ph the most favorable ph value - the point where the enzyme is most active - is known as the optimum ph this is graphically in addition to temperature and ph there are other factors, such as ionic strength, which can affect the enzymatic reaction each of these physical. The enzyme catalase, found in potato juice, was used for the catalyst along with a substrate known as hydrogen peroxide (h2o2) the job of catalase in this experiment was to accelerate the breakdown of hydrogen peroxide into water and oxygen gas after looking and recording how different concentrations of a substrate. Activity by measuring the rate at which o2 is produced when h2o2 is exposed to catalase at differ- ent ph levels and temperatures your task design two controlled experiments to determine how changes in temperature and ph levels affect the activity of the enzyme catalase the guiding question of this investigation is,.

Different tissues in the body have different phs (ph is a measure of how basic or acidic a solution is) the liver maintains a neutral ph (about ph 7), which is easiest for its enzymes, such as catalase, to work in consequently, when exposed to hydrogen peroxide the liver should have produced more. Changes in ph also alter an enzyme's shape different enzymes work best at different ph values the optimum ph for an enzyme depends on where it normally works for example, intestinal enzymes have an optimum ph of about 75 enzymes in the stomach have an optimum ph of about 2 graph showing temperature. Lab report on measuring the rate of conversion of hydrogen peroxide using enzyme catalysis in essence, the main objective was to use chemical titration to other purposes of the lab were to measure the effects of changes of temperature, ph, enzymes concentration, and substrate concentration on rates of an enzyme. Leaving cert experiment to investigate the effect of ph on the rate of enzyme activity focusing on the rate of catalase activity on hydrogen peroxide.

Answers to discussion questions on the effect of temeperture onenzyme action picture temperature affects the reaction rate of enzymes, as do ph, substrate concentration and enzyme concentration in the following experiment the activity of catalase is measured and graphed over a range of temperatures. However there are many factors which affect the rate of enzymes reactions one of them is ph, which influence on the enzyme activity will be the subject of this investigation catalase of potato tuber cells will be the enzyme used in the experiment research question what is the influence of different. Like all enzymes, catalase helps the reaction but does not itself get used up in the reaction also like other enzymes, catalase must have a proper environment in which to work your body's enzymes, for example, work best when your temperature is normal (around 37˚ c) and when the ph is between 73 to 74.

Measuring the pressure of the product as it appears (in this case, o2) in this experiment, you will measure the rate of enzyme activity under various conditions , such as different enzyme concentrations, ph values, and temperatures it is possible to measure the concentration of oxygen gas formed as h2o2 is destroyed using. Each lab station is set up to perform a different section of the lab exercises (a-f) increasing enzyme (catalase) concentration (part a) increasing substrate (h2o 2) concentration (part b) changing ph (part c) changing ionic concentration ( part d) changing temperature (e) increasing concentration of enzyme inhibitor. Concentration of enzyme: the sweet potato was blended, diluted, and filtered to create a liquidly sweet potato solution each sample of the solution has the same amount of catalase for each trial temperature of variables: the temperature of the sweet potato, hydrogen peroxide, ph, and all other. Then you will discover the effect of: a) temperature – repeating the same experiment at different temperatures b) ph – repeating the same experiment at different ph values c) enzyme concentration – the same experiment but using different quantities of catalase d) substrate concentration – the same experiment but using.

Problem: how could certain factors of ph and temperature could affect enzymes hypothesis: ph: ph could affect the activity of the enzyme (catalase) what we could have done to take this experiment to the next level is choose different vegetables with catalase enzymes to see if the results are the. The enzyme is not altered by the reaction you have hundreds of different enzymes in each of your cells each of these enzymes is responsible for one particular reaction that occurs in the cell in this lab, you will study an enzyme that is found in the cells of many living tissues the name of the enzyme is catalase it speeds.
