What effect does temperature have on enzymes? 

# data[].attributes.body
Temperature can greatly effect  enzymes in many ways. For one thing when the temperature becomes to high the active spot and the proteins begin to change shape and deform. Also the enzymes begin to go at a slower pace and move slower than their supposed to.

What effect does the burning wood have on test tube 4? Why is the flame produced?

What effect does the burning wood have on test tube 4? Why is the flame produced?

# data[].attributes.body
In test tube 4 the wood splint created a fire when it was submerged in the foamy substance. The flame was produced because pure oxygen is flammable. The foamy substance was made of oxygen and water, making very flammable.

In test tube 2 what happened when the liver was added? What gas was produced? What liquid was left behind ?

In test tube 2 what happened when the liver was added? What gas was produced? What liquid was left behind ?

# data[].attributes.body
In test tube 2 when the liver was added a foamy and bubbly reaction occurred. Oxygen was being produced along with some water. The peroxide was being left behind.

Enzymes are made of proteins and help the body produces faster chemical reactions. They are required to be able to live.

In this experiment my hypothesis was correct. I suspected that the liver would create water and oxygen from the peroxide. This in fact happened in the form of a foamy substances aka bubbles. During this experiment I learned that the body produces harmful substances like peroxide and its up to functions to turn it into a not harmful substance. I all so learned why the liver is so important, because it does the functions mentioned above.

Reactions per test tube:
1- Water and liver= no reaction
2- Peroxide and liver = foaming substance that could be oxygen and water, but we don't know yet.
3- Peroxide and wooden splint with ember= no reaction ( peroxide isn't flammable)
4- Peroxide and liver with wood splint ember- the peroxide and liver caused a foamy substance, then the wooden ember causes a fire when submerged .

In the 4th test tube again put around 2 cm of peroxide in the test tube. Then place a piece of liver into the test tube. As the foaming substance begins to bubble, set a wooden splint on fire and wait until its almost out, then submerge it in the foam. When it is submerged a fire will be started. This is because the foam is pure oxygen and water, and pure oxygen is flammable.

In step three you again fill the tube with about 2 cm of peroxide. Instead of putting liver in it, however, light a wood splint on fire. wait until the splint is almost burned out, then place it in the peroxide. Nothing happens when you do this because peroxide is not flammable.

In the 2nd test tube, fill it up about 2 cm with peroxide. Then like in step 1 place a piece of liver in the test tube. By doing this you should get a foamy reaction. But what is this foam. Is it oxygen?

# data[].attributes.body
Fill the first test tube with about 2 cm of water. Then take a piece of liver and place it into the test tube. Wait to see the reaction. There is no reaction, because we left the peroxide out.

My hypothesis on this lab is that i think that the enzymes will work in the liver to turn the peroxide into water.

In this lab we tested to see if the liver and its enzymes will break down peroxide and turn it into water and oxygen.
