Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

Stallings Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a reaction for the reason

Unit One: Animal Structures and Functions‚ Answers to Review Questions Respiratory System 1. Indicate the importance of gas exchange in all living organisms. Respiration is gas exchange (Oxygen and Carbon Dioxide) with the external environment. All living things respire. Gas exchange is important so that cellular respiration can take place and energy can be made for the cells. 2. Distinguish among the terms cellular respiration‚ external respiration and internal respiration

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‚

Abstract: Enzymes‚ molecules that speed up chemical reactions‚ are specific to one substrate. In this experiment the substrate hydrogen peroxide and the enzyme catalase will be used. The higher the concentration of potato extract‚ or catalase‚ the faster the reaction and the more substrate present will result in a decrease in the time of the reaction. The amount of concentrations of enzymes and substrates are changed to determine if the reaction is further catalyzed by a greater concentration of

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

“Aren’t you excited to be a senior now that you’re finally in Grade 11?” my mother asks with a worried look‚ as she puts her small cappuccino on the kitchen table. “Yeah‚ I guess I am quite pumped being a senior now at my new school‚” I answered “Don’t worry‚ dear. You will be fine today‚” she says with a warm smile. “My advice for you is to be yourself.” “I am a shy‚ boring person‚ mom. I just don’t relate to other people.” I stated. “I am only interested is blending in with the crowd‚ acing all

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

About 25‚000 people die from cirrhosis each year. Description/Definition Cirrhosis is a consequence of chronic liver disease characterized by replacement of normal‚ healthy liver tissue by fibrotic scar tissue‚ blocking the flow of blood through the organ and preventing it from working as it should‚ as well as regenerative nodules leading to progressive loss of liver function. The liver‚ the largest organ in the body‚ is vital in keeping the body functioning properly. It removes or neutralizes poisons

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs
