Conclusion In a prior lab‚ it was given that the enzyme Aspergillus oryzae (fungus) works best at warm temperatures and an acidic pH‚ porcine (pig) works best at body temperature (37 ºC) and

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

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

Studying the Rate of Reaction of catechol oxidase and how it affects pH levels Introduction: In this lab‚ we studied the activity of an enzyme that is found in fruits and vegetables called catecholase or catechol oxidase. An enzyme is a protein molecule that is a catalyst. Catechol oxidase is the enzyme in fruits and vegetables that turns them that undesirable brownish color; also commonly referred to as bruising or bruised. When walking through your regular grocery store and you find yourself in

the activation energy of either the creation or breaking apart of a chemical bond. By lowering the activation energy of this process‚ the reaction of bonding‚ or in this case breaking apart‚ is sped up. An enzyme breaks apart the substrate in the active site of the enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case‚ the enzyme is catalase and the substrate is hydrogen peroxide‚ or 2H2O2. As the catalase and the substrate interact‚ the

Hypothesis: For an increase in a normal force‚ there will be a corresponding increase in friction. Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment‚ I am using a contact force‚ a force that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount
