In this lab we will see how this works. My hypothesis of this lab is that the catalase will break down the hydrogen peroxide into water and oxygen just as it does in our everyday bodily functions]]> 2017-06-26 02:18:28 UTC https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177405401 hunter_bass700 https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177405580 5 Test Tubes
Water
Hydrogen Peroxide 
Eyedropper
4 Liver Pieces
1 Match
2 Wooden Splints ]]> 2017-06-26 02:21:34 UTC https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177405580 hunter_bass700 https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177406859 Step 1: Collect materials needed
Step 2: Add 2cm of water to test tube 1
Step 3: Add 1 piece of liver to test tube 1 (push liver down if needed into the water)
Step 4: Fill test tube 2 with 2cm of hydrogen peroxide.
Step 5: Add 1 piece of liver to test tube 2 (push into peroxide if needed)
Step 6: Add 2cm of hydrogen peroxide to test tube 3
Step 7: Light wooden splint with a match, wait until it is glowing red and insert slowly into test tube 3
Step 8:  Add 2cm of hydrogen peroxide into test tube 4
Step 9: Add 1 piece of liver to test tube 4 (push down liver to peroxide if needed)
Step 10: Light another splint with a match now wait until it is glowing red and place the glowing part on the reaction bubbles in test tube 4.  Light splint again if needed.
Step 11: Boil 2cm of water and 1 piece of liver in test tube 5
Step 12: Add 2cm of peroxide into test tube 5.
Step 13: Observe your reactions in all 5 test tubes]]> 2017-06-26 02:41:01 UTC https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177406859 hunter_bass700 https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177407806 Here is a chart showing how the test tubes reacted.]]> 2017-06-26 02:58:35 UTC https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177407806 hunter_bass700 https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177409035 1. What are enzymes?  What are their roles in chemical reactions?  Enzymes are proteins that act as a catalyst for reactions in organisms.  In chemical reactions enzymes speed them up.  Without this boost by the enzymes it would be hard for most organisms to perform internal functions needed to stay alive.

2. Describe what happened to test tube 2 when hydrogen peroxide was added to the liver.  What gas was produced?  What liquid was left behind?  When hydrogen peroxide and the liver met in test tube 2 there was a bubble reaction.  The gas of the bubbles was oxygen and the liquid left was water.

3.  What effect does the red hot wood have on test tube 4? WHY is the flame being produced?  In test tube 4 there was another oxygen-water bubble reaction. The red glowing wood starts fire with the oxygen but the water takes it back out. The flame is produced because in typical fires the reason the flame burns is because of oxygen. Oxygen burns when brought to the high temperature of the red glowing wood.

4. What effect does temperature have on the enzymes (Test tube 5)? The enzymes denature, meaning they bend in shape and no longer will work to make the oxygen-water bubble reaction. When temperature is raised to any enzyme they denature]]> 2017-06-26 03:23:20 UTC https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177409035 hunter_bass700 https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177409887 In this lab we learned that liver does a vital bodily function thanks to science! Without the liver turning toxic peroxide into oxygen and water using the enzyme catalase, no animals would be able to live in our ecosystem. So therefore my hypothesis was also correct, the liver reacted with the peroxide and created a oxygen-water bubble reaction]]> 2017-06-26 03:42:16 UTC https://padlet.com/hunter_bass700/2qzu3gdb7m9b/wish/177409887
