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

DIGESTIVE ENZYMES AND THEIR FUNCTIONS Mouth -the oral cavity or the mouth contains salivary glands that secrete a wide range of enzymes to aid the first step of metabolism of food. The salivary gland secretes the enzyme lysozyme which has an antibacterial action. The enzymes secreted by the mouth mainly provide protection against bacteria. Betaine helps to maintain a fluid balance inside the mouth. The lists of digestive enzymes secreted by the oral cavity are mentioned in the table. Enzymes | Function

of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different enzyme can be found in any cell. Enzymes can be describe as molecules

The Effect of Enzymes on Apple Juice Production Biology Period 6 Background Info The purpose of this experiment was to determine which enzyme or the combination of the two enzymes makes the most apple juice from applesauce. We did his by‚ mixing 10 drops of an enzyme (cellulose/pectinase/both) into a few tablespoons of applesauce. We then left the rest to nature‚ and watched the liquid funnel out for 10 minutes. Lastly‚ we recorded our data. The cell wall is a complicated

RUNNING HEAD: Understanding Enzymes Understanding Enzymes Amanda Chung Blanche Ely High School Abstract The researcher conducted this experiment in order to investigate how various factors effected enzymes. Those factors were the concentration of the enzyme‚ the temperature it had to work in‚ and the pH level of the solutions as well. All three were hypothesized to speed up the rate at which the enzyme acted. A series of several tests were carried out to find the answer to each problem

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction

Adding Enzymes to Improve Beef Tenderness By Chris R. Calkins‚ Ph.D. and Gary Sullivan‚ University of Nebraska Importance of Beef Tenderness Beef palatability is affected by many factors and tenderness is cited as one of the most important. Consumers are willing to pay a premium for a guaranteed tender product with the potential to increase the value of the middle meats over $60 per carcass (Miller et al.‚ 2001). Consequently‚ the meat industry is in a continual search for methods to improve the

15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site of enzyme to transfer in to one or

The Effect of pH on the Rate of Enzyme Catalysis of Catalase Objectives: The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. More specifically‚ the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. Introduction: Enzymes are proteins that act as catalysts for reactions. This simply means that enzymes lower the activation energy required

HB105: Introductory Physiology The Action of Enzymes Introduction An enzyme is located in all living cells‚ and is a complex protein molecules. These protein based molecule act as a catalyst. This is a compound that aids chemical reactions without its own structure and state being changed during the process. Catalysts speed up chemical reactions‚ changing substrates into specific produce. Without these enzymes life would not exist. Enzymes are fundamental to all living things as they speed up
