The Enzyme Concentration and The Volume of Juice As the enzyme concentration increases so too does the volume of juice. This is because as the concentration of enzyme molecules increase there is more chance of a collision with an apple substrate molecule. If the chance of a collision is increased then the number of collisions will increase resulting in a higher rate of reaction. The enzyme combines with the substrate to form an enzyme-substrate complex. Enzyme + Substrate ¬¬¬> Enzyme-Substrate
at various enzyme concentration (graph 1), the increase of enzyme dilution results in a slower decrease of amylose percentage. Looking at the graph, the amylose percentage decreases at a fast rate with the undiluted enzyme. However, the enzyme dilution with a concentration of 1:3 decreased at a slow rate over time. Additionally, the higher the enzyme dilution, the higher the amylose percentage. For example, in the graph it can be seen that the enzyme dilution with a 1:9 concentration increased over
Background Information Enzymes are proteins that serve as biological catalysts in a wide variety of life sustaining chemical reactions that take place in cells. As catalysts, enzymes lower the activation energy it takes a chemical reaction to occur. Because of this enzymes serve to speed up the rate at which the chemical reactions can occur. However, enzymes are substrate specific. This means only one kind of enzyme will bond with one kind of substrate on the active site, the place where the chemical
The Effects of Enzyme Concentration on the Activity of Amylase To investigate the effect of Amylase concentration on its activity. the relative activity of Amylase is found by noting the time taken for the starch substrate to be broken down, that is, when it is no longer gives a blue-black colour when tested with iodine solution. This time is referred to as the achromatic point. Equipment: v Amylase solution 0.1% v Starch Solution 1.0% v Distilled water v Iodine in potassium
Investigating the Effect of Enzyme Concentration on the Hydrolysis of Starch with Amylase Aim: Investigate the effect of enzyme concentration on the rate of an enzyme-controlled reaction. Using amylase and starch as my example. Introduction: I am investigating the effect of the concentration of the enzyme, amylase on the time taken for the enzyme to fully breakdown the substrate, starch to a sugar solution. The varied variable will be the concentration and all other variables are going
shows that as enzyme concentration increases absorption also increases. In this case absorbance can be used to measure the enzyme’s activity, the higher the absorption the higher the activity. Since absorption increases as enzyme concentration increases, enzyme activity is promoted by increased enzyme concentrations. After a certain point enzyme activity would fail to increase as a result of increased enzyme concentration since there wouldn’t be enough substrate for all of the enzymes to react with
the time of conducting the experiment, the intention was to analyse the effect that an increase in catalase concentration had on the amount of oxygen (O2) produced if the hydrogen peroxide (H2O2) concentration was constant. It was proposed that when the catalase increases in concentration at the increments of 0.5%, 1%, 2%, and 4% and the hydrogen peroxide remained at a fixed concentration, the oxygen production would rise gradually. It was suggested that this would occur due to the collision theory
Background An enzyme is a biological catalyst which speeds up biochemical reactions, such as digestion and respiration, but they remained unchanged at the end of the process (Walpole, Merson-Davies, and Dann 53). Problem Question What is the effect of the substrate concentration on enzyme activity? Hypothesis As the concentration of the substrate increases, the rate of reaction also increases until it reaches its maximum point where all enzyme molecules are already active due to the solution becomes

Introduction This is a real A-level school project and as such is intended for educational or research purposes only. Extracts of this project must not be included in any projects that you submit for marking. Doing this could lead to being
Analysis of the Enzyme Sucrase for Optimum Temperature, pH, and Concentration ABSTRACT Enzymes react differently under different conditions and concentrations, being the most productive at the enzymes specific optimum condition and concentration. The enzyme sucrase, extracted from yeast, breaks down the complex sugar sucrose into the simple sugar glucose. Testing for sucrase’s optimum environment, multiple reactions were ran using varying amounts and concentrations of sucrose and sucrase at

(H O ) Prediction: I predict that with the higher concentration of enzyme, the likelihood of it breaking down molecules will be greater because there will be more enzymes to work at the substrate and the chances of it colliding will be higher making the activity
Investigating the Activity of an Enzyme Sucrose using the enzyme sucrase (invertase) can be broken down into Glucose and Fructose. The aim of this experiment was to find about the activity of enzymes through measuring the micromoles of sucrase expressed whilst the following reaction occurs:- SUCRASE [IMAGE]SUCROSE GLUCOSE + FRUCTOSE C12H2201 H20 C6H12O6 C6H12O6 The progress of this reaction was monitored using Dinitrosaylic Acid (DNS) as the reagent reacts with the
Immobilized Enzymes (Yeast) Abstract Catalase is an enzyme found in living cells and is used to break down peroxides. Yeast cells, which contain catalase, are used to catalyse the decomposition of hydrogen peroxide solution into water and oxygen gas. The yeast cells were immobilized in sodium alginate beads in this experiment. Immobilized enzymes are widely used in biotechnology processes. They can be reused and is more stable at extremes of temperature and pH, thus improves the economy
sequences, producing differing protein structures and functions. An enzyme is a specialized protein that participates in chemical reactions where they serve as catalysts to speed up said reactions, or reduce the energy of activation, noted as Ea (Mader & Windelspecht). The way an enzyme decreases the energy needed is through
An enzyme can be defined as a protein that acts as a catalyst in a biological system. It increases the rate of reaction by decreasing the activation energy. The catalytic power and specificity of an enzyme can be altered by the binding of certain molecules. These molecules are referred to as inhibitors. An inhibitor works to prevent the formation, or to cause the breakdown of an enzyme-substrate compound. There are two categories of inhibitors. The first being irreversible inhibitors, and the second
amylase when adding copper sulphate to a starch solution. Introduction Enzymes are that act as catalysts, in other words they increase the rate of chemical reactions. Consider the following general reaction between two substances, A and B, which react together to form a product, substance C: A + B = C In biological systems, this reaction might occur very slowly, or not at all, in the absence of an enzyme. Enzymes will greatly increase the rate of formation of the product. They can increase
Enzymes Enzymes are biological catalysts. A catalyst is defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanentchange. Enzymes do precisely this in living things. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Enzymes have two main functions: To act as highly specific catalysts, and also to provide a way of controlling reactions, the amount of enzyme determines how quickly the reaction
reaction also known as enzyme kinetics involves enzymes which are catalysts which speed up a reaction without being used up itself and do not appear as reaction products. Kinetics measures the rate of a chemical reaction to help determine the concentration or quantity of the enzyme of interest. Km and Vmax are used as constants in any enzyme reactions. (1) Vmax is known as the maximum velocity at which the reaction can be catalysed. It is used to measure the enzymes concentration and is found when all
assessment was to research, design and conduct an experimental investigation on the effect of substrate concentration (manipulated by increasing concentration of pH buffer) of catalysed reactions by measuring the volume of oxygen produced as the reaction proceeded. Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being altered itself. Enzymes are also proteins that fold into complex shapes that allow smaller molecules to fit into them. The
