Enzymes assist by catalyzing (accelerating) the reaction and decreasing the activation energy necessary for it to take place. Some enzymes are affect Enzymes are complex proteins that cause a specific chemical change in all parts of the body. The name of the enzyme is catalase; it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into two harmless substances → water and oxygen. Diseases or defects passed down through families (inherited) can affect how enzymes work. An enzyme may be denatured by high temperatures. Catalase is one enzyme from liver that breaks down harmful hydrogen peroxide into oxygen gas and water. 37c is the natural temperature of your body, and your liver which is where Catalase is, so it would work the best in this temperature which is why it produced the most amount of oxygen there. Practice and apply hypothesis testing. Catalase catalyzes the breakdown of hydrogen peroxide to water and oxygen: 2 H 2 O 2 → 2 H 2 O + O 2. Do not cook it, cooking will break down the enzyme so it won’t work. They are biochemical catalysts meaning they lower the activation energy needed for a biochemical reaction to occur.
