Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

Title: Enzyme Activity Lab Purpose: To measure the rate of enzyme activity from a tissue abstract and experiment with different factors‚ such as the enzyme solution and the substrate with different hydrogen peroxide percentages and temperature‚ that affect enzyme activity. Hypothesis: 1) If the disk is placed into each beaker with 100 units/ml of enzyme solution‚ then the time for the disk to float will be 30 seconds. 2) If the temperature of the solution is at 5 degrees Celsius‚

Affect of enzyme concentration to the rate of reaction Aim: With the experiment of protein solution‚ in this case egg white added to different pepsin concentrations (0%‚ 0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%) shows‚ as the egg white is a protein and the pepsin works as an enzyme‚ how a higher pepsin concentration and therefore a larger amount of enzymes effect the rate of reaction. Hypothesis: An increased concentration of pepsin speeds up the time the mixture needs to come clear. Introduction:

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of

Six Factors Affecting the Performance of an Enzyme Enzymes are considered catalysts; substances that increase the rates of reactions. Enzymes are responsible for thousands of metabolic processes that involve the sustainment of life‚ one common one is simple food digestion. Without enzymes‚ digestion would occur too slowly for life to continue. Enzymes maintain a protein structure consisting of one or possibly more than one polypeptide chains of defined primary structure‚ and take up a characteristic

The purpose of this investigation is to find out the relationship between the substrate concentration and the rate of reaction. Substrates are molecules that are acted upon by enzymes. For instance‚ amylase‚ an enzyme found in saliva
