Catalase

1 enzyme Enzymes are biological catalysts. A protein compound Energy can reduce the carbon reaction. Enzymes to accelerate specific types of reactions. And the kind of substance that reacts. 2.1.1 catalysis of enzymes E is a catalyst (enzyme). S is a precursor called chop, nitrates and substance P is a product. E + S ---------------> E S ---------------> E + P. Complexometry 2.1.2 Factors affecting the enzyme. 1) What type of controlled…

research by Bode Science Center this bacteria is a rod shaped but comes in many different types of bacilli and may trigger local infections such as peritonitis, meningitis, appendicitis, and a bloodstream infection (Rauhut, n.d.). This bacteria is Catalase, oxidase, decarboxylase positive. It does not ferment any sugars nor sulfur. It is motile but also can be no motile. This bacteria is a strict aerobic bacteria that was isolated from fecal matter and then later discovered it is also found in…

the rate of reaction of the enzyme catalase. The biological catalyst called enzymes increase the rate of reaction without themselves being chemically changed. Enzymes are globular proteins folded into a complex 3-dimensional shape that contains a special surface area called the active site where a specific substrate binds structurally and chemically. Enzymes speed up reactions as they lower the activation energy. In this experiment, the enzyme used is catalase; which is found in both plant cells…

peroxide solution (10°C, 20°C, 30°C, 40°C, 50°C, 60°C) This is used to determine the rate of the enzyme catalase reaction. Dependent Variable The dependent variable are the values, which depend of the independent variable. The height of the froth in the test tube when the liver cube is reacted with hydrogen peroxide. The height of the froth is determined by the rate of the of the enzyme catalase reaction at varying temperatures. Constant Variables A constant variable are variables that…

Peroxisomes execute various metabolic functions and create hydrogen peroxide as a byproduct from the process of oxidation. However, since the hydrogen peroxide created by the peroxisome is toxic, the organelle also produces an enzyme called “catalase”. The catalase enzyme breaks down the hydrogen peroxide and converts it into water (Alberts, 2002). For an example, peroxisomes in the liver detoxify alcohol by converting the toxin’s hydrogen into oxygen. Peroxisomes also accomplish metabolic…

The oxygen becomes the gas and the water becomes the foam. Unlike the cow liver that was dropped into water, it did not react. The enzyme catalase was not activated to break anything down thus having no change on the cow liver. Conclusion: Based on the evidence stated above, the hypothesis is supported because the hydrogen peroxide ended up breaking down the cow liver emitting gas and foam…

Weakness Explanation Suggestion(s) for improvement Not measuring the temperature of the liver cubes that are the sources of the enzyme catalase. Although the hydrogen peroxide solutions were at the desired temperatures, it was uncertain whether their paired liver cubes had the same temperatures. This places concern on whether the froth height was close to being accurate, hence reliable. If the temperature of a liver were lower than the desired temperature, the enzymes would be less likely to…

Cells contain organelles they aren’t touched basis on, that also play a very important role into the cell as far development goes. Many of the organelles operate off of other to maintain its specific duties with the human body. One in particular are considered to be peroxisomes. Peroxisomes have digestive enzymes in relations to lysosomes, but they have special bodies that allow it to work in low level regions in which wouldn’t be supported elsewhere inside of the specific cell. Peroxisomes…

enzymes are important to many bodily functions. Catalase is one of the enzymes essential to cellular health within the body. It is responsible for the breakdown of hydrogen peroxide which, if it builds up, is extremely toxic to cells. One question that scientists have asked and a question that we explore in this lab is what are the optimal conditions for this reaction to occur? This lab was designed to test for the most ideal pH and temperature in which catalase could work most efficiently on a…

enzyme is 37°C, the closest temperature recorded to that temperature was 32°C. At this temperature, the reaction rate decreased instead of gradually increasing. This shows that the catalase performed best at the temperature of 55°C instead of the optimum temperature of an enzyme, 37°C. The reaction rate of the catalase at 55°C was 91.25 mL/min compared to 32°C which had a reaction rate of 83.5 mL/min. The rate of reaction was slowed at 32°C and was higher at 55°C which contradicts biological…
