tissues containing catalase Having three different substances allowed us to determine whether each contained catalase.
Test Tube 1: Potato and H2O2 Test Tube 2: Apple and H2O2 Test Tube 3: Chicken and H2O2 For our first test tube, containing potato (Image 1), we discovered that the potato did in fact contain catalase. We proved this by adding 2 mL of H2O2 to the potato. Our reaction rate was 3 (around 9 seconds), making it the slowest to stop bubbling. In the second test tube (Image 2), we did the exact same testing as we did for our first test tube. When we added the apple to the H2O2, it started bubbling pretty fast and ended pretty fast. Our reaction rate for this one was 4 (around 6 seconds), making it the fastest to bubble so far. As you already know, our last test tube consisted of chicken (Image 3). Adding the chicken to the H2O2 almost had the same reaction as the apple. It had the same information as our second test tube. |
higher/lower concentrations of catalase By doing the enzyme experiment with apple, potato, chicken, and liver it showed us that all different kinds of tissue contain catalase. It doesn't mean that they all have the exact same amount. We have examined that the potato had the most catalase because it released the most 2H2O and O2 gas. We also observed that the potato had a reaction rate of 3 because the reaction lasted about nine seconds. The apple and chicken were rated about a 4 because both of their reactions lasted around six seconds.
We noted that the more the substance bubbles the higher concentration of catalase it has. Because of that, the lower the substance bubbles, the lower concentration of catalase it contains. |
catalase helps maintain homeostasis
Maintaining homeostasis means being able to maintain your internal stability. Catalase is a big part of maintaining homeostasis. The human body must contain homeostasis to live. Without catalase, the human cells will be poisoned and die and without cells, the human body would not be able to function properly.
Enzymes increase the rate of chemical reactions. A catalase is and enzyme that breaks down hydrogen peroxide, hydrogen peroxide is a poisonous chemical. the catalase brakes down the H2O2 into 2H2O and O2 which are harmless gasses. Without catalase the body would not maintain homeostasis.
