Enzyme

The lab that is being preformed is about digestive enzymes. Enzymes are protein molecules produced by living organisms that speed up a specific chemical reaction in the body. There are also digestive enzymes which digest our food. Our bodies make digestive enzymes in the pancreas, stomach, small intestine, and mouth. Digestive enzymes break down the food we eat into nutrients so that our bodies can absorb them. There are different digestive enzymes that digest certain macromolecules such as…

An enzyme is a biological catalyst; they accelerate most reactions within cells (Cooper, 2000). Enzymes have three constitutional characteristics: they assist chemical reactions without becoming exhausted or altered themselves, they do not change the balance between the reactants and products and they are highly specific as to what reactions they are able to catalyse (Cooper, 2000). The active sites of enzymes are where chemical reactions occur. The active sites are dimples or grooves in the…

INTRODUCTION: The objective of this lab is to measure the activity of an enzyme and the effects of environment conditions on enzyme activity. Enzymes are catalysts; agents that speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature. For this lab report we focused on the enzyme Tyrosinase, Tyrosinase is an enzyme that produces melanin from the amino acid tyrosine. Three different reactions…

An enzyme is a protein catalyst, whose basic function is to increase the rate of the reaction, meaning lowering the activation energy. Because the body creates enzymes to be as specific as possible, in order to prevent inefficiency and careless mistakes, most enzymes come in direct contact with only one substrate to produce products. Enzymes will work on creating substances until the reaction is complete or the particular enzyme is inactivated, which either means being destroyed & recycled or…

Enzymes are a biological catalyst. When a chemical reaction is taking place the enzyme works to lower the activation energy of a reaction. The activation energy is, the amount of energy that is required in order for a reaction to take place. Enzymes bind to reactant molecules. The enzymes hold these molecules in a way that makes the processes of the chemical bond-breaking and bond-forming take place more readily. A reaction can be either energy-releasing or energy-absorbing. Enzymes have no…

introduce the basics of enzymes. The topic is important because they are in every living cell and because of enzymes chemistry is allowed in the cell. They do this by providing the energy needed for chemical bonds to break down and lets molecules interact with each other. For part 1 of the lab my hypothesis was if you increase the concentration, then the absorbance will also increase. For part 2 section A my hypothesis was if you increase the temperature, then the enzyme reaction time will also…

Abstract The purpose of this investigation is to determine whether the temperature can affect the reaction rate of enzyme activity. The enzyme activity was measured by five different temperatures, separated in tubes which later got measured by their height of foam after 10 minutes. Freshly-prepared potato juice was used as the enzyme for catalase. Since temperature is measured by the kinetic energy of molecules, the higher the temperature, the more movement of molecules. The lowest temperature…

In this experiment, the effects of environmental conditions on enzyme activity are explored. An enzyme is better known as an element produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. The environmental condition that was examined were the effects of temperature on enzyme activity. The raw materials that were used in this experiment were potato pile used to create catechol oxidase, catechol, and water which added as the solution. With Pipets and…

The catalytic effect and specificity of enzymes 1.Introductions to enzymes Enzymes are proteins that can react with their specific substrates to achieve an highly effective catalyst reaction. .Almost all cellular activities of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts，enzymes provides another reaction route requires lower activation energy (Ea) to increase the number of particles that have a kinetic energy of not less than…

Effects of Temperature and Substrate Concentration on Catalase Kristen Clark Biology 101 Lab Section 041 9/22/14 Brandon Stroup Abstract Catalase is an enzyme found in every living organism and is essential for cells. This lab explores how catalase reacts to four different temperatures and how the concentration percentage of substrate affects its reaction rate. The performance of catalase is dependent on many factors, so the purpose of the lab was to find the ideal concentration and…
