LAB: Substrate Concentration Affecting the Rate of Enzyme Activity: Through the Experiment of Beef Liver Puree and Hydrogen Peroxide Research Question Does different amount of substrate affect the rate of enzyme activities? Purpose To examine how different types of concentration (Hydrogen Peroxide) affect the rate of enzyme activity. Hypothesis We believe that if there is more substrate concentrated‚ then there will be an increase in the rate of enzyme activity. This is because

pH indicators‚ in chemistry‚ are usually a weak acid or base that are naturally occurring in various plants and flowers and can act as dyes. Some examples of indicators are Litmus (Comes from a plant species called a lichen)‚ Phenolphthalein‚ Thymol blue‚ Bromocresol green and Universal indicator. All these indicators have a certain turning point in color once a certain concentration equilibrium of Hydrogen cations in reached (H +) or a certain concentration equilibrium of H3O+(Also OH - using Arrhenius

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs

Danny Fish 10/9/11 Chemical Testing To identify An Unknown The hypothesis tested was that depending on the solution presented‚ which would test positive for one of the following‚ proteins‚ carbohydrates‚ or lipids through use of chemical testing. (Sudan IV‚ Benedicts’ Solution‚ Iodine‚ Biuret’s) . In order to gain more information for the hypothesis‚ one must know how to test for said macromolecule. Each of the above stated molecules has their own individual solution that will in turn identify

Exploring Enzymes - Ground-Up Tissue Activity Abstract Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined

The Effect of pH on the Rate of Enzyme Catalysis of Catalase Objectives: The objective of this lab was to develop a protocol to investigate the effect of an environmental variable on the catalytic function of an enzyme. More specifically‚ the objective was to perform an experiment in order to test the effect of pH on the function of the enzyme catalase. Introduction: Enzymes are proteins that act as catalysts for reactions. This simply means that enzymes lower the activation energy required

Lactose Intolerance is an intestinal condition caused by insufficient synthesis of the intestinal enzyme lactase needed to break down lactose (Keith‚ Nichols‚ Reed‚ Kafer‚ Miller 2011). So what does this exactly mean? People with lactose intolerance have trouble digesting lactose‚ the natural sugar found in milk and milk products. Undigested lactose can upset the stomach and cause diarrhea. Most people who are lactose intolerant are able to consume some lactose without symptoms. However‚ many people

Introduction: Lactose intolerance is defined as the incapacity of the human body to digest the disaccharide sugar molecule‚ lactose. Lactose is a common carbohydrate found primarily in milk and associated dairy products. This widely known gastrointestinal disorder is typified by symptoms like nausea & vomiting‚ bloating‚ flatulence‚ abdominal pain and even diarrhoea. Lactose intolerance is a non-fatal disorder of the gastrointestinal tract. It is simply a nuisance and relatively harmless in and
Premium Milk Lactose intolerance
The lactose is milk sugar‚ a disaccharide consisting of one glucose and one galactose. When lactose reaches the small intestine‚ the lactase enzyme acts on the lactose found in ingested food‚ dividing it into the two molecules that compose it‚ so they can be absorbed‚ digested and transported through the bloodstream. When the person has a lactase deficiency (lactase enzyme has a low concentration or does not occur)‚ the dietary lactose cannot be digested in the small intestine directly passing into
Premium Glucose Enzyme Metabolism
Introduction Enzymes are protein based structures that help speed up chemical reactions. They help these reactions keep up with the everyday metabolic needs and other like functions of organisms. Enzymes are also considered catalysts‚ due to the lowering in activation energy‚ in which they are not consumed or changed at any point during the reaction. These enzymes have three main protein structures that help keep them formed and intact. Stage 1 of these structures is the primary structure‚ which
