Enzymes are organic catalysts that speed up the rate of reactions. ]]> 2018-02-15 15:56:48 UTC https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231970683 slmalta https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231971553 If liver is exposed to peroxide, then it will break the peroxide down into water and oxygen. ]]> 2018-02-15 15:58:06 UTC https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231971553 slmalta https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231973749 Liver, water, peroxide, stick, fire, five test tubes, boiled liver]]> 2018-02-15 16:01:22 UTC https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231973749 slmalta https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231974278 In the lab, first test tube 1 is filled with 2 cm of water and a piece of liver. Test tube 2 is filled with 2 cm of peroxide and a piece of liver. Test tube 3 is filled with 2 cm of peroxide. A stick is lit on fire, blown out, and inserted into test tube 3. Test tube 4 is filled with 2 cm of peroxide and a piece of liver. The stick is lit on fire again and inserted into test tube 4. Put boiled liver in peroxide in test tube 5. ]]> 2018-02-15 16:02:12 UTC https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231974278 slmalta https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231976023 In test tube 1, no reactions took place. In test tube 2, a reaction took place that create bubbles. In test tube 3, no reaction took place. In test tube 4, a fire is created. ]]> 2018-02-15 16:04:52 UTC https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231976023 slmalta https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231977166 I have accepted my hypothesis. Test tube 1 proves that water does not produce a reaction. When the liver was added to the peroxide in 2, the liver broke down the peroxide, producing oxygen and water and causing bubbling. 3 proves that peroxide is not flammable. In 4, the red hot wood causes a fire. This is because the reaction of the liver and the peroxide created water and oxygen. The pure oxygen, which is highly flammable, caused the fire. In test tube 5, we proved that overheated enzymes do not react as fast. In test tube 5, boiled liver and peroxide didn't react at all. One thing I learned was that overheating liver enzymes will prevent them from reacting. This applies to my life because if I have a fever, it could slow down my body's removal of toxic substances. Some mistakes that could have occurred are adding too much peroxide or too much liver. ]]> 2018-02-15 16:06:46 UTC https://padlet.com/slmalta/3bd7hvmbyj3j/wish/231977166
