Omar Shbeeb Toothpick Enzyme Lab 9/25/13 Introduction Enzymes are used in all metabolic reactions to control the rate of reactions and decrease the amount of energy necessary for the reaction to take place. They are responsible for the thousands of chemical interconversions that sustain life. Enzymes are referred to highly selective catalysts‚ meaning they speed up the rate of metabolic reactions. To react‚ they need to find a perfect match with a substrate. They converge at a place called an

Plasmid Grant Zarrinmakan‚ Berkley Kruschke‚ Erika Lawrence. Wed/Fri‚ D-Block‚ 12-January-2015 Introduction Transformation is the genetic alteration of a cell resulting from the direct uptake of exogenous DNA from its surroundings. By doing this lab‚ we will answer the essential question: What influences transformation efficiency? Although there are many possible influences‚ our hypothesis is that plasmid has a positive influence. To test this hypothesis‚ we will set up an experiment in which we

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

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

This lab is adapted from the canned denatured pineapple experiment. Instead of investigating the effect of canning on enzyme activity‚ we look for the presence of the substrate. This is a useful teaching lab for all the criteria and requires very few resources. Background Information: Gelatin is made from a protein called collagen which comes from the joints of animals. Gelatin may be dissolved in hot water. As the dissolved gelatin mixture cools‚ the collagen forms into a matrix that

Enzymatic activities of bioactive washing powder Title: Investigation of the amalyse activity f bioactive washing powder Objective: To investigate the amalyse activity of the two brands of bioactive washing powder – “Super clean” and “Magic power”. Principal: Amalyse can catalyse the breakdown of starch into maltose. In this practical‚ solutions of the 2 washing powders will be filled into 2 identical wells on the starch agar plate separately. Starch will be broken down by the amylase disused

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 reactions. All proteins are made up of amino acids (Johnson‚ 2010). The purpose of this experiment is to determine whether peptide bonds are present in various food substances. The color violet will indicate the presence of

Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food

Research Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine.
