Immobilized Enzyme Immobilized Enzyme * Enzymes which are attached to small bead made of alginate are called immobilized enzyme * However‚ whatever the nature of an immobilized enzyme‚ it must comprise two essential functions‚ namely the non-catalytic functions (NCF) that are designed to aid separation and the catalytic functions (CF) that are designed to convert the target compounds within the time and space desired * Immobilized enzymes might meet the increasing demand by manufacturers

Biology Digestive Enzyme Experiment “Design an experiment in which you will investigate a digestive enzyme’s effect on digestion” Research Question: To determine the effect of enzyme concentration on the rate of digestion. This will be done by increasing the concentration of the enzyme diastase and investigate its effect on the rate of starch digestion. The rate will be determined by the amount of time it takes to completely digest the powdered starch‚ the complete digestion will be indicated by

this particular enzyme and determined whether the lactase came from human cells or bacterial cells. In the statistical analysis statistical formulas and techniques are used to analyze the significance of a set of data and the validity of the conclusions made based on that data. These are some terms and definitions that will be crucial to understanding the validity of this experiment. An enzyme is a protein that acts as a catalyst to lower the activation energy required for reactions to progress in

Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values‚ subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 | | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 | | 0

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

Interpretation of Data When looking at my results i can safely say that the change in HCl concentration does affect the rate of reaction with the Calcium carbonate pebbles. The relationship between the change in HCl and reaction rate can be seen in the graph and raw data table presented above. If you compare the lowest concentration with the highest concentration you’d be able to see that there is a very large contrast between their averages. The average gas production of 0.1M HCl was 0.00693 kPa/s

Rate of Reaction Experiment Introduction : in this term in chemistry class I was learning about rate of reaction. As defined by the Britannica encyclopedia‚ a chemical reaction is a process where one or more substances (reactants) are converted to one or more different products because of the rearrangement of atoms of the reactants. For the reaction to occur‚ the particles must collide with each other and in order to succeed there must be enough energy for the collision because a collision with little

in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease in weight as the concentration increases. The independent variable in this experiment would

RUNNING HEAD: Understanding Enzymes Understanding Enzymes Amanda Chung Blanche Ely High School Abstract The researcher conducted this experiment in order to investigate how various factors effected enzymes. Those factors were the concentration of the enzyme‚ the temperature it had to work in‚ and the pH level of the solutions as well. All three were hypothesized to speed up the rate at which the enzyme acted. A series of several tests were carried out to find the answer to each problem

Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the
