Optimum Temperature Lab Report
RESULTS
28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers.
Based on the results from the graphs, at extreme temperatures such as 0⁰C which is extremely cold and 100⁰C which is tremendously hot; catalase activity performed better at 0⁰C than at 100⁰C. Strangely, 50⁰C outperformed 37⁰C. Catalase activity was higher for intermediate temperatures such as 37⁰C and 50⁰C than the extreme temperatures such as 0⁰C and 100⁰C. Overall the rate of reaction peaked at 28⁰C and every other temperature had a lower maximum rate of reaction.
DISCUSSION
The results do not support the hypothesis that optimum temperature would be at 37⁰C. The results do not reflect the textbook narrative of enzyme activity. Enzymes are supposed to peak at optimum temperature and then temperatures further away from the optimum temperature should result in decreased rate of reaction.
This means the cooler 37⁰C is a worse condition for catalase than 50⁰C. In normal circumstances, temperatures away for ideal temperature put a strain of the hydrogen bonds that hold the active site on enzymes. This can lead to breaking of the hydrogen bonds that maintain the shape of the active cite. Rate of reaction is supposed to decreased continuously as more enzymes cannot form enzymes-substrate complex because of a denature active sites as a result of higher kinetic energy supplied to the enzymes from raising the temperature beyond the optimal

The purpose of this investigation is to figure out how temperature, pH, and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to occur, allowing vital processes such as digestion, ATP production, and DNA replication to occur efficiently. Using a Vernier Gas Pressure Sensor the rate of reaction of the enzyme catalase as it decomposed Hydrogen Peroxide in a test tube was measured and then results were put on the screen of a Macintosh computer using Logger Pro software and Vernier computer software. Several trials were then done with one factor, either temperature, pH, or enzyme concentration being altered, while the remaining two stayed constant. The rate of reaction of catalase should increase with enzyme concentration until a certain point until it reaches its limit. For temperature the rate of reaction of catalase should increase until the enzyme catalase denatures, and then after the rate should start to decrease. When exposed to different pH levels the rate of reaction of catalase should increase as the enzyme catalase reaches its optimal pH level, once it’s at that point the rate of reaction should then decrease as the pH level goes farther away from catalase’s optimal pH level. The data for the trials of pH and enzyme concentration support the expected hypotheses of how the reaction rate would be affected, however the data did not support the hypothesis made for the effects of temperature on an enzyme’s reaction rate due to divergent data from the expected results. (need this line or is conclusion and results of data and trends summarized with data supported hypotheses) ask if titel too long,,…

The prediction for the effects of temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased, until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity, shown as the last point on the fig 8 and 9, do not fit on the graph. The optimum temperature was about 47 degree C. The core body temperature is only about 37 degree C and thus these enzymes are operating below their optimum temperature.…

The rate of enzyme activity is highest when the temperature is the highest and lowest when the temperature is lowest. The temperature causes the enzymes to speed up and produce more product when heated and slows down when cooled. This is seen in the data gathered during the temperature part of the lab.…

The temperature range over which enzymes show activity is limited between the melting point (0oC) and boiling point (100oC) of water. If a temperature is too low, there can be no noticeable reaction rate since the enzyme is operating at a temperature far below its optimum. If the temperature at which the enzyme is operating at is well above 100oC, then thermal deactivation can…

If i was to design this investigation again, I would use more temperatures than just 4 to give a wider range to experiment with. Also, i would have used more than one catalase because it gives you a chance to see which catalase can work the best under each temperature. Finally, I would instead of using water and heating it up, I would use a different substance for example alcohol or juice. To verify our data, I would repeat the experiment 20…

The rate of catalytic reactions is affected by the changes in temperature, pH, enzyme concentration, and substrate concentration. Each enzyme has an optimal temperature at which it is most active; the rate of reaction increases with increasing temperature up to the optimal level, but drops sharply above that temperature. Most enzymes have their optimal pH value that range from 6 to 8 with exceptions, and they may denature in unfavorable pH levels. An increase in enzyme concentration will increase the reaction rate when all the active sites are full, and an increase in substrate concentration will increase the rate when the active sites are not completely full.…

Temperature factor prediction: I predict as the temperature increases, the enzyme activities will increase because there is more energy to speed up the reaction until it reaches the optimum temperature range (room temperature which is about 20 °C), and after that the enzyme activities will decrease because of denature of the enzymes (cause changes to active site that will no longer fit substrate)…

Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism's closely controlled internal environment. In such a homeostatic environment, the temperature and the pH (concentration of hydrogen ions), remain within a fairly narrow range. Extreme variations in pH and temperature denature the enzyme by altering its chemical structure, thus adversely affecting the chemical reaction. As even the slightest change in the protein's structure will change the enzyme's shape enough to prevent the formation of the enzyme-substrate complex, the reaction will then be unable to take place. The enzyme, catalase, reacts with hydrogen peroxide in order to yield water and oxygen. Therefore, upon reaction, bubbling will occur as oxygen is produced. The amount of bubbling, or oxygen that is produced is dependent on the conditions under which the reaction takes place (or fails to).…

The increase in temperature increased the rate of reaction up until 50ºC. After 50ºC, the rate of reaction quickly reduced to near 0. Refer to figure 4. The data supports our hypothesis. At temperatures from 0ºC to 50ºC, as temperature increases, so does the kinetic energy of the molecules. With a higher kinetic energy the molecules move faster and more PNPP will collide into phosphatase 's active site more often and the reaction would be catalyzed faster. This explains our positive relationship of increasing rate of reaction as we increased temperature. However, temperatures after 50ºC, the rate of reaction due to phosphatase immediately drops to near 0. This can be explained that at high temperatures and high levels of kinetic energy, the tertiary structure of phosphatase is altered along with the active site so PNPP can no longer fit and be catalyzed. Phosphatase is no longer able to catalyze the reaction at these high temperatures and has become denatured. The highest rate of reaction occurred at a temperature at 50ºC. Around 50ºC would be the optimal temperature for phosphatase efficiency, and if found in nature, phosphatase is expected to be in an environment of 50ºC. A follow up experiment could involve finding phosphatase in nature and seeing its environmental temperature to see if it coincides with our optimal temperature. Also, to establish a better curve, we could test the rate of reaction of phosphatase at more temperatures around the suspected optimal, maybe 45ºC and 55ºC to more accurately determine the optimal…
