Enzyme

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective…

the accuracy of separation. The purpose of Experiment 5-2 is to purify the E. coli enzyme, β-Galactosidase through the use of affinity chromatography on P-aminobenzyl-1-thio-β-D-galactopyranoside agarose, which is a good substrate for the enzyme. This enzyme will be eluted at high pH. The Bradford assay will be used to determine the protein concentration and the specific activity of the solutions containing the enzyme. Size-exclusion chromatography separates molecules…

Enzymes are catalysts that contain proteins. Catalysts are the part of the product that speeds up a reaction. Only reactions can occur when the right enzyme ends up finds the right material to produce a process. A low pH is a good environment for an enzyme as well as a low temperature. After the reaction, no enzymes are used up. They can be used again and again in reactions, once an enzyme is used in one reaction, it can be used in another. Enzymes are made up of proteins and proteins are made…

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…

Abstract: Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes.The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate. Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site…

November 3rd, 2014 A Period Abstract: This report is a demonstration of different conditions an enzyme is exposed to and how the enzyme reacts in response. The conditions the enzyme was exposed to include: ideal conditions, the presence of a competitive substrate, denaturation for a short amount of time, and complete denaturation. The enzyme being observed was an imaginary one called “toothpickase”. This “enzyme” was to break toothpicks without any obstructions, the presence of paperclips as…

1.)During the lab and based on recorded observations it can be deduced that the enzyme catalase found in potatoes only reacted to hydrogen peroxide. This is do to the fact that before 10 ml of hydrogen peroxide was added to each test tube residing 3 potato samples and the designated liquid, no reaction was observed. Thus demonstrating the catalase's inability to react to vinegar, soda, water, detergent, and Na OH. Furthermore, shortly after the hydrogen peroxide was added to the liquids of…

The Effect of Change in Temperature Conditions on Enzymes Bacillus licheniformis Amylase and Aspergillus oryzae Amylase Over Time ____________________________________ Roxanna Flores PID: 5199946 Lab Section U26 Group Members: Roudabyna Taleb Abstract This laboratory was performed in order to be able to determine the effect of temperature over time on bacterial amylase Bacillus licheniformis and fungal amylase Aspergillus oryzae. Bacterial amylase was introduced into four singular test tubes…

rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points. Enzymes are effective by reducing the activation energy. The enzyme tyrosinase is located in melanocytes. These are cells that produce the pigment melanin. Melanin gives skin, eyes, and hair their color.…

The purpose of conducting this experiment was to explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it…
