Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables‚ such as temperature‚ and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place

Testing Catalase Activity Prepared by Anel Behric For professor Goodrow General Biology Lab Mohawk Valley Community College 10/14/2014 6:00 PM Introduction: This experiment was conducted to examine the breakdown of substrate hydrogen peroxide (H2O2) by catalase‚ which is a specific enzyme that breaks down substrates of (H2O2). Molecules are in our bodies and nature. They move around constantly which causes them to be part of random collisions‚

Determination of presence of protein in a variety of food substances by the use of Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates‚ lipids‚ and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Cruelty Involved in Animal Testing Hobbes‚ the cat‚ has been under experimentation for most of his life. This is probably the last time that he will ever have to be experimented on again. Why? Because he is probably not going to make it through this time. The makers of Herbal Essences are about to force shampoo down his throat to see what happens to its organs. Even if the cat lives through the process‚ they will have to kill it to see which organs were affected by the toxic chemicals. If this

purple/violet d) In a positive test for lipids the substance would leave a translucent stain on the brown paper bag 2. The purpose of testing the four test tubes was to ensure that the colour change that occurred in the substance was due to a chemical change and not the substance being added to it. 3. The student saw a colour change happen because the heat causes the biuret to chemically react with the protein. The reaction should change the colour of the mixture from blue to purple in appositive test
