Chemical Reaction Essay

It was hypothesized that the optimal pH for the enzyme was pH 7 while the 1.0 ml peroxidase would have the best reaction rate. At the end of the experiment the results prove the hypothesis to be incorrect. INTRODUCTION Enzymes are proteins that allow a reaction to speed up. These proteins are made up of monomers known as amino acids.

Introduction In class, a series of experiments were performed that pertained to the enzyme known as catalase, which converts hydrogen peroxide into oxygen. Due to peroxide being toxic to the tissues of both plants and animals, both possess the enzyme catalase, which breaks into two non-toxic compounds: water and oxygen gas. Enzymes are proteins that react to certain substrates to create a product, and continue doing so afterwards. Methods and Materials To test reactions between catalase and hydrogen peroxide, groups of three to four people were formed.

In an organism 's body, chemical reactions are constantly taking place. These essential reactions can make or break the well-being of the body, yet the brain behind these changes is often times not recognized. This little brain or “macromolecule” is called an enzyme. An enzyme is a type protein that is able to speed up over 5,000 different reaction types an organism (2). Through catalyzation, the process of speeding up chemical reactions, enzymes attach to a substrate/molecule and break it down so that it can be used throughout the organism.

Four types of reactions will be performed in this experiment: precipitation reactions, redox reactions, decomposition reactions, and acid base

Tyler White CHEM151LL 32658 04/01/2018 Different Types Chemical Reaction Types and Equations Purpose: The purpose of this lab experiment is to examine different types of chemical reactions such as Decomposition reaction, Synthesis reactions, Combustion reactions, and different Chemical equations. The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.

For example, you put hydrogen gas and oxygen into a room. A little water might come out of it. But if you add a spark, an exothermic reaction explosion might occur. Single reactions often occur as a small part in a big reaction.

Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of

The highest reaction rate during the lab was with a temperature of 30℃, which makes sense since catalase is found in the liver at a temperature of 37℃ (Buddies, 2012). The temperature of 30℃ was the closest to catalase’s normal temperature which is why it yielded the highest reaction rate. Therefore, in order for the body to discard the toxic hydrogen peroxide, the body must constantly maintain a temperature of 37℃ to prevent cell damage (Sciencing, 2018). At extreme temperatures, an enzyme’s activity will decrease because enzymes have a very narrow range in which they can effectively function. The results from the lab show that at 100℃, catalase has no reaction with hydrogen peroxide.

Observing the effects of a catalyst on an enzyme’s rate of reaction Leong, M., Kim, E., Nair, A. Achilly, K., 9/22/2015 Introduction: An enzyme is a protein that acts as a biological catalyst. A catalyst increases the rate of reaction by reducing the activation energy required (Reece 2005). Catalase, an enzyme produced by most living organisms, catalyzes the decomposition of H2O2 in our bodies in order to maintain homeostasis.

Title: Enzymes Abstract: Enzymes can catalyze chemical reactions by speeding up the chemicals activation energy. Temperature and pH are just two of the factors that affects enzymes and their involvement with chemicals and the way they function. Throughout this experiment, we conducted a study on peroxidase, which is an enzyme. The following information consist of the recordings of when it was exposed to four different pH levels to come up with an optimum pH and IRV at the end. Introduction: Enzymes are proteins that are used in reactions in living organisms.

The purpose of this study is to investigate the effects of varying the concentration of peroxidase on rate of reaction, as well as, the varying temperature and pH levels. Enzymes are proteins that catalyze biochemical reactions that work by reducing the activation energy for each reaction, causing an increase to the rate of the reaction. One class of enzymes are known as peroxidase. Peroxidase catalyze the oxidation of a particular substrate by hydrogen peroxide. Meaning that it eliminates H2O2 in order to prevent damage to the cells and tissues (Department of Biology University of Tampa 74).

An enzyme is protein that acts as a catalyst. Catalyst is a chemical agent that increases a chemical’s reaction rate by decreasing the activation energy (initial energy). In this experiment we used Turnip Peroxidase as our enzyme. It was primarily designed to find out if changing different factors such as, the enzyme concentration, temperature, pH and an inhibitor could have an effect on the enzyme’s activity.

Introduction When a chemical reaction occurs anywhere in the universe, it needs energy. The human body is no exception. For some reactions, the energy required to start the reaction is Enzymes are special proteins designed to assist in the breaking down of macromolecules. They do so by holding the macromolecule in place at the active site, therefore lowering the amount of energy it takes to start the chemical reaction. There are different enzymes for each macromolecule; Pectinase and Cellulase are both examples of enzymes, and were the enzymes tested in this lab.

They can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.

The purpose of this experiment was to analyze the effects of the variables: temperature, pH, and enzyme concentration, on the enzymatic reaction rate of catalase and the level at which its products are released, measuring the rate of absorption using the indicator solution guaiacol and a spectrophotometer to develop a hypothesis of the ideal conditions for these reactions. My hypothesis is that the extremes in concentration, temperature and pH will negatively affect the Au rate. This experiment used 11 solutions contained in cuvettes. Each cuvette, once mixed, is placed in spectrophotometer and then a reading taken every 20 seconds. Cuvettes 1, 8, and 10 are used as blanks to zero out the spectrophotometer.
