Hydrogen peroxide

Discussion Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…

Effects of Temperature and Substrate on Catalyst Enzymes Ryan Smith Lab Section 030 Abstract In order to turn hydrogen peroxide into water and oxygen by using enzyme called a catalyst. To determine the effects of temperature and substrate concentrations we preformed an experiment testing the effects on the catalyst enzyme reaction. The hypothesis for our first experiment was if the substrate concentration is larger than the catalyst enzymes activity will be faster as well. The result followed…

photochemistry and, lastly, antioxidant systems that scavenge toxic compounds. Stress can induce the uncoupling of the light and dark reactions that results in the formation of dangerous reactive oxygen species (ROS)such as superoxide radical (O2-), hydrogen…

Catalase?”) This experiment involved both of these two aspects. It was inferred before the experiment began that if the potato is placed in hydrogen peroxide at room temperature, then it will produce the most bubbling activity. The reason that the potatoes produced a bubbling activity is because hydrogen peroxide is an example of a catalase. Hydrogen peroxide is a chemical compound with the formula H2O2. It is made of 2H2O which is water, and Oz which is oxygen. (Corsini, "What Is a…

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…

Hemoglobin has a peroxidase-like activity, meaning that it will break down hydrogen peroxide, or other organic hydroperoxides. This makes it useful in forensics, since you can test for the presence of hemoglobin simply by dropping hydrogen peroxide on it. Of course, there are a lot of things that have peroxidases in them, so this is a presumptive test for the presence of blood. Blood cells are not immortal; each cell wears out in about four months, and will disintegrate in the blood stream,…

individually while writing this practical report. While conducting the investigation, I had to work with my partner in a safe and considerable manner to allow the experiment to be completed safely. The person that I was collaborating with poured the hydrogen peroxide solution into the measuring cylinder with the liver it and marked the froth volume, while I timed the whole procedure. We both kept an eye out on the temperatures of the water baths and the temperature of the kidney and solution…

are inside of nearly every living organism that is exposed to oxygen. Some examples of catalase enzymes are bacteria, plants, and animals. The main job of a catalase enzyme is to catalyze the decomposition of hydrogen peroxide to water and oxygen. When an enzyme is exposed to hydrogen peroxide or certain other chemicals it is prone to react. Catalase enzyme reactions also depend on the temperature they are exposed to. As enzymes are exposed to cool temperatures they vibrate less. They do not…

can change the speed with which the substrate and enzyme bind together. When temperatures are higher they move at faster speeds, which could cause the hydrogen bonds to break. The pH values can change the 3D shape of the proteins and, therefore, influence how well the substrate and enzyme bind together. When high temperatures are reach the hydrogen bonds break and the 3D shape is changed. When boiling the enzyme or extract, such high temperature result in a permanent change in the structure of…

Hydroponic Food Production Introduction Since ancient times human beings have learned to work the earth in order to survive. With the pass of time humans have developed different ways to improve productivity when cultivating plants. This is particularly important with the increase in human population, lost farm lands and climate changes. (Arteca) Currently there are a couple of different methods to cultivate plants. Even thou Although all of them have the same objective of generating…
