We also want to prove that when enzymes are heated past their optimal temperature, they will not work as efficiently.]]> 2017-02-15 01:00:47 UTC https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153900443 Hypothesis whiteywhitey14 https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153900519 My hypothesis is when the liver is exposed to the peroxide alone, it will cause a reaction and the peroxide will turn into water and oxygen. Also, when the heated enzymes interact with the peroxide, the reaction will not be as efficient as the reaction from the previous tests. ]]> 2017-02-15 01:01:27 UTC https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153900519 Materials whiteywhitey14 https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153900718 The materials needed to conduct this experiment are:
- A cup of water
- 5 test tubes
- Box of matches
- Wooden splints
- Peroxide
- 4 pieces of liver
- 1 eyedropper
- Heat source]]> 2017-02-15 01:03:08 UTC https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153900718 Procedure whiteywhitey14 https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153901630 To start off the lab, we take the eyedropper and fill the first test tube with about 2 cm of water. We then place the piece of liver in test tube number 1. This will be our control. Next, we will fill test tube number 2 with approximately 2 cm of peroxide. We will then place another piece of liver inside test tube number 2. After this, we will again fill test tube number 3 with about 2 cm of peroxide. Then, we will set one of the splints on fire, let it burn for a while, blow it out, and quickly place it inside the peroxide to see if it is flammable. Then, we will fill test tube number 4 with 2 cm of peroxide and a piece of liver, then set another splint on fire, let it burn for a while, then blow it out. Then quickly, touch it with the reaction from test tube 4. This is used to truly see if the reaction gives off water and oxygen because oxygen plus heat will spark a fire. Finally, we place a piece of liver inside test tube number 5 along with some water and boil it for a little while. Then we will put some peroxide inside the test tube and see if a reaction occurs. ]]> 2017-02-15 01:11:01 UTC https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153901630 Results whiteywhitey14 https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153902647 2017-02-15 01:20:19 UTC https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153902647 Conclusion whiteywhitey14 https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153907355 After the lab, I came to the conclusion that my hypothesis was correct. The lab clearly shows that the mixture of peroxide and liver gives off oxygen and water because the heated splint caused a spark on the reaction. We saw this first in test tube 2 when it first gave off water and oxygen and it left the peroxide behind. This shows that the enzymes in our bodies release oxygen and water when they break down our food. We also found that the boiled liver had a smaller reaction compared to a piece of liver at its ideal temperature. ]]> 2017-02-15 02:00:46 UTC https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153907355 Things to know before the lab whiteywhitey14 https://padlet.com/whiteywhitey14/cnm0ohpd5es6/wish/153908638 Enzyme- an enzyme is found in the human body and their purpose is to break down food.
