BIO 5 Lab Report: Lactase Enzymes Enzymes are biological catalysts or assistants. Enzymes consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient. Enzymes can either launch a reaction or speed it up. The chemicals that are transformed with the help of enzymes are called substrates. In the absence of enzymes‚ these chemicals are called reactants. Enzymes are thought to have an area with a very particular shape. When a molecule of

The data from the experiment demonstrates that the catalase enzyme breaks down the hydrogen peroxide due to its harmful toxicity to the liver. In section A‚ the effect surface area has on the enzyme was tested. The results have proven that as the surface area increases‚ the reaction rate of the enzyme also increases. To illustrate‚ when the liver was ground‚ the bubbles from the reaction reached a maximum height of 150mm in five seconds less than the unground liver which merely reached a maximum

experiment were to investigate the activity of enzymes‚ components that influence the enzyme’s activity‚ identify an unknown phosphatase‚ influence of inhibitors‚ and determine if inhibition is competitive or noncompetitive. A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown phosphatase analyzed

20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place

Introduction Enzymes are proteins produced by living organisms to speed up the rate in which chemical reactions occur. This process can happen fast‚ slowly‚ or stop the chemical reaction all together depending on the temperature‚ pH and concentration. Catalase is one of the most common enzymes. It is found in living organisms and is used to break down hydrogen peroxide. This must happen because hydrogen peroxide is considered toxic to cells in the body. However‚ when catalase is used it breaks

Enzymes Abstract: The following 2 labs experimented the more enzymes and substrates added to the concentration will effect the reaction rate. Our second lab‚ we tested enzyme and substrate concentrations to determine the increase of temperature and inhibitor. The enzyme source used in both labs was peroxide‚ guaiacol is used as a substrate for peroxide. We used Guaiacol‚ turnip extract‚ peroxide and distilled water for enzyme and substrate concentration. In the second lab we used the same substances

Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

The cells in the solutions of distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions
