    Elizabeth Au (1) Serena Chan (3) Sharon Chan (4) Christy Chan (5) BIOLOGY LAB REPORT Investigation of the effect of metal ions on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive inhibitors

    Chavez Period 1‚ Bio Acc. Mrs. Petrov October 1‚ 2014 Tyrosinase Enzyme Lab Question What are enzymes and how can we cause changes in enzyme function? Objective The objective of this experiment is to observe if changes in temperature will cause a disruption in enzyme function. Hypothesis If we add and boil enzyme in L-Dopa‚ then the color will become darker because the temperature will denature some of the enzymes. Variables Independent: Temperature Dependent: Color change Control:

    was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a

    ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise

    Chemical Reactions Lab Introduction Four different types of chemical reactions were observed in this lab. Synthesis reactions occur when two different elements or compounds form a more complex compound as shown by equation (1). Single replacement occurs when one element replaces another to form a new compound as shown in equation (2). Double replacement occurs when two different atoms in different compounds trade places with one another to form two new compounds as shown in equation (3).Combustion

    Enzyme Specificity Using Beta-galactosidase and Alpha-galactosidase Introduction: In order to survive‚ organisms need reactions to occur at a certain time and place. Enzymes make these reactions happen. Enzymes are highly specific causing only one enzyme to catalyze one reaction. “Induced fit” explains why enzymes act this certain way. An enzyme will surround a certain substrate and form to it for the reaction to occur in the active site. If it doesn’t form to it‚ the reaction will not occur

    Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

    Restriction Enzymes Restriction enzymes (also known as restriction endonucleases) are a group of bacterial enzymes which cut double-stranded DNA (dsDNA) into smaller fragments at specific points. They are a defence mechanism used by bacteria to cleave the DNA of invading viruses‚ thereby restricting their expression. The exploitation of restriction enzymes ability to cut large pieces of DNA into smaller fragments (called restriction fragments) and the highly specific way in which they do this

    Title: You Light Up My Life Purpose: To determine how different environmental conditions affect a plants starch levels. Hypotheses: 1. If the plant that is in absence of CO2 and is kept in a closed environment‚ then it will have a starch level of 1 because the plant is missing CO2‚ which it needs to complete the photosynthesis process. 2. If the plant is in a closed environment‚ then the plant will have a starch level of 3 because it has all the environmental conditions it needs. 3. If the plant
