[Name] [Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction‚ but it always has the same impact. However‚ certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction‚ depending on the

trend O2 production and reaction velocity increased with increasing catalase concentration‚ however‚ the 33% percent catalase concentration showed a drop of 0.175 mL O2/s compared to the 25% catalase concentration (figure 1.2). The velocity of 25% catalase was 0.275 mL/s‚ 33% was 0.1 mL/s‚ 50% was 0.435 mL/s‚ and 75% catalase was 0.575 mL/s (figure 1.1). The 50% catalase concentration produced the most O2 overall however the 75% catalase concentration had the fastest initial reaction velocity. Experiment

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but it would

affect the optimum operation of enzymes. These condition include temperature‚ enzyme concentration‚ substrate concentration‚ acidity‚ salinity‚ and any present activators/inhibitors. In this particular lab‚ temperature was the environmental factor studied. More specifically‚ the enzyme catalase and its substrate hydrogen peroxide were tested under different temperatures. It was discovered that‚ temperature can affect the optimum operation of enzymes; The enzyme catalase has an optimum operation condition
Premium Enzyme Metabolism Catalysis
Enzymes are biological catalysts or assistants that consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. They can either launch a reaction or speed it up. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). The catalase used in this experiment will come from five different sources: Spinacia

Enzymes are proteins produced by living cells of that act as catalysts which affects the rate of biochemical reaction by speeds up the breakdown of hydrogen peroxide into water and oxygen gas. The students have formed a hypothesis toward this experiment. If the speed of

Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon.

Introduction: Catalase is an enzyme‚ which is present in all life forms that utilize oxygen for their biological processes. Enzymes are proteins which increase the rate of reaction by decreasing the activation energy (the energy required to initiate a reaction). One of the main function of Catalase is to prevent the accumulation of hydrogen peroxide (H2O2) in the body by breaking it down into water and oxygen gas. Hydrogen peroxide is a toxic by-product of metabolic reactions. If hydrogen peroxide

until the enzyme reaches its optimum point of saturation‚ after which any increase in the substrate concentration will no longer affect the rate of reaction. The independent variable in this investigation is the varying concentrations of the substrate (Hydrogen Peroxide: 1%‚ 3%‚ 5% and 6%)The dependent variable was the rate of enzyme catalase activity‚ which was measured by the volume of froth produced after one minute.The concentration and volume of liver extract (source of catalase) used was kept

Catalase is a common enzyme found in the bodies of all living organisms in contact with oxygen. It is involved in reacting with hydrogen peroxide to convert it into water and oxygen and can do so with millions of hydrogen peroxide particles each second. These types of enzymes have many uses in bodily systems commonly known as proteins that speed up the rate of the metabolic process by regulating the chemical process which helps digest food and break down toxic substances. The most favourable conditions
