>The results of the lab were very accurate because the r action of the enzymes in hot water were actually very quick and in cold water the enzyme mess seemed to react very slow. Background: So far from what we have learned from 3. 2. 1 about enzymes is that they are substances that produce a living organism that acts as a catalyst to bring a SP specific biochemical reaction. Enzymes are very important because they control the s peed of chemical reactions in the body, but also enzymes are made out of amino acid s and have a lock and key basics.

What this does is that it lock the enzymes and the key substance and the only way it will react is by inducing the correct substrate, which plays a role in determining the final shape of the enzyme and so the enzyme partially flexible. Chemical digestion is a process in which food is being broken down by chemic in our bodies like saliva and enzymes. Besides their being enzymes there are also consumes which support the functions of enzymes, they loosely bind to enzyme mess to help them complete their activities, they are nonprofit, and they are organic molecules.

Our goal in the experiment was to see the different reaction that happen to enzymes while being at different temperatures. For an example when we did the lab we saw that the pressure in warm water was high which lets us know that enzyme nature at a warm temperature, and we placed some ice on the beaker the temperature began to decrease and when we took the pressure, the result SSH owed that the enzymes reacted very slow which seems to give us a very obvious result. When enzymes are in a cold temperature they tend to have less energy and have a I ate reaction.

Hypothesis: My hypothesis on this experiment was that enzymes would move very fast in warm temperature and that in a cold temperature the enzymes would be MO vying slow or like being stiff and that their reaction would decrease from what it would reach at a high temperature. Materials and Methods: 1. Use a 600 ml beaker and fill it up with warm water up 250 ml. 2. Use a thermometer that measures in Celsius, take the temperature of the water, results should be around 19 co 3. SE a hot plate and heat it up to a low temperature and then place the beaker with the thermometer on the hot plate and let it sit their for 5 minutes 4. After 5 minutes have passed remove the beaker from the hot plate take a look at your experiment, the temperature of the water should've gone up unlike the group, their results were chic 5. Avian the beaker removed from the hot plate, make sure you get a flask that is 125 ml. 6. Fill the flask with 50 ml of hydrogen peroxide and place it inside the 600 ml beaker. 7. Once you have done that use the fernier to measure the gas pressure 8. You need to connect the USB cable to your computer and the other end of the cable connect it to the labiates box and connect the cable to channel 1 9. After connecting the gas pressure sensor open the program on your computer and make sure you're starting off with a blank graph 10. Then grab the gas pressure sensor and connect it to labiates box with a lack cable. After doing that grab the valve and the rubber stopper. 11. Once you have everything connected the fernier use a microcomputer that measures 2020041 12. SE a pipette and put it on the microcomputer and absorb 10041 of catalyst 13. Poor the amount of catalyst in the in the flask and quickly and cover the flask with the rubber stopper. 14. Make sure you put pressure on the rubber stopper and click the green button on the computer which begins to graph. 15. You should only do this for 200 seconds and wants you're done you click on the red icon which means stop and then print out your results. 16. You Should now do a cold water bath and to be able to do this you need ice and fresh new enzymes and hydrogen peroxide.

Make sure you dump out all the liquids you used and get fresh ones. 17. Remember thou should fill the beaker with 250 ml of cold water and pour 50 ml of hydrogen peroxide in the flask. You should have some ice and put some in the beaker and take the temperature of the cold ice water, you should NOT use the hydrogen peroxide yet. 18. After 5 minutes the temperature that the group recorded at first, was ICC Make sure you record your results 20. After taking the temperature of the water. Owe you should take the hydrogen peroxide and get it close to the temperature of the water. 1 . 19. Get the flask that contains the hydrogen peroxide and place it back In the beaker, let it sit there for about 10 minutes. 22. When 10 minutes have passed you should now use the fernier and repeat steps 715 again. Rest Its: The results of this experiment was that the enzymes react very slow in cold w eater and that in hot water the enzymes have more energy and are able to move m such faster. The slope in the graph for hot water was y=0. 0119 and so that was the change e for every second and the slope for cold water was 0. 03 which lets you know that the c hanger in both slopes was decreased from what you can see, Results of the different temperatures in Celsius cold water coco hot water coco cold ice water cold ice water beaker/flask Discussion: We already know that enzymes denature do to the type of temperature there at The results of the graph for hot and cold water show that the pressure thee r is when the enzyme is found at a hot or cold temperature. The important liquids that we used in this experiment was O 2 ( hydrogen peroxide) and the catalyst. The enzymes destroy hydrogen peroxide by breaking it down.
