Enzyme Lab

The lab about catalase enzyme was cool because it showed how our cells can make dangerous stuff, but they don't get harmed. We learned that enzymes, like catalase, are tiny helpers that speed up reactions in our cells, making harmful things safe. The lab let us see this in action, as we watched catalase turn a bad chemical called hydrogen peroxide into harmless water and oxygen. We used bits of pork liver and mixed them with hydrogen peroxide to see what happens. When the liver was at normal temperature, it made lots of bubbles, and when it was cold, it still made bubbles but not as much. The warm liver and the one in the special liquid didn't do as well, and the liver in the acid liquid didn't do anything at all! We found out that catalase likes it best when it's cold. It's like enzymes are picky about their surroundings. We also learned that the enzyme can be used over and over again This made me realize how amazing our bodies are and biology is to be more interesting than first perceived.
