object or evaluation. This report aims to conclude whether there is a difference between female and male attitudes towards smoking. It is hypothesised that females will have a more positive attitude towards smoking. Questionnaires using a 5 point likert scale will be utilised to measure each participants’ attitude towards smoking through their responses. Results stated there is no significant difference between genders when scores were placed through an independent t-test. It is concluded that more

are many conditions of the environment that can affect the optimum operation of enzymes. These condition include temperature‚ enzyme concentration‚ substrate concentration‚ acidity‚ salinity‚ and any present activators/inhibitors. In this particular lab‚ temperature was the environmental factor studied. More specifically‚ the enzyme catalase and its substrate hydrogen peroxide were tested under different temperatures. It was discovered that‚ temperature can affect the optimum operation of enzymes;

Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The chemical reaction is shown as 2H2O2 = 2H2O + O2 (Keilin and Hartree 397). The reaction involves primarily the adsorption of hydrogen peroxide at the catalase surface. The decomposition of hydrogen peroxide by catalase is regarded as involving

purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

The methodology includes procedures; multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures that are neither freezing nor boiling‚ catalase performs well in lower concentrations than the substrate

To begin this test‚ 3 water baths were set up. One bath was cooled to 0 degrees celsius‚ one was heated to 37 degrees celsius‚ and one was boiled to 100 degrees celsius. 1 of the four test tubes containing 2 ml of 100 units/ml catalase was put in to each of the three water baths‚ one at a time. While the tubes sat in the baths‚ the 4 H2O2 vials were prepared and the depth of the H2O2 was recorded. After the 0 degree celsius test tube incubated in it’s bath‚ it was taken
