The Effect Of Enzyme Concentration On Enzyme Activity The pancreatic duct in individuals who have cystic fibrosis frequently becomes blocked‚ reducing or preventing the release of pancreatic enzymes into the small intestine. The aim of this activity is to investigate the effect of a reduction in enzyme concentration on the rate of reaction‚ in this case the breakdown of protein by protease enzymes. Aim – Milk powder contains a white protein called casein. A white suspension of

Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react with

Erica Osorio 5057497 Christian Roque and Rogerlio The Mechanisms by which E.Coli Cells Developed Immunities toward Ampicillin due to Plasmid and DNA Consumption U34 Abstract During the ampicillin experiment the ability to transform cells to make them adaptable to their environment was studied. The E.coli bacterial cell was used in order to observe how its DNA was able to change and develop immunity towards ampicillin. In order for this change to occur the use of several

I. Purpose/Problem/Question Which type of friction is the largest force – static‚ sliding‚ or rolling? Which is the smallest? II. Background Information From our previous activities that we did in class‚ I know that static friction is a very large force. The force is larger than rolling‚ sliding‚ and fluid friction. I also learned that rolling friction is the smallest type of force. This information may connect to my final analysis. III. Hypothesis If static friction is the largest force

Abstract The objective of this science fair project is to determine the effectiveness of using sugar to preserve and keep the flowers fresh for longer periods of time. The experiment will be carried out using flowers such as the pompons‚ alstroemeria‚ sunflowers and water containing different amounts of sugar Hypothesis Flowers that are in contact with a more concentrated sugar solution will be able to last longer. Background Keeping flowers fresh "Beautiful" and "sweet-smelling" are

Molecular Biology Lab Report Payton Jackson Introduction In this lab‚ I am going to use antibiotic-resistance plasmids to transform Escherichia coli. Materials For this lab you will need the following: LB Agar Petri dishes Beakers Test tubes CaCl2 solution Sensitive E. coli (-ampR) amp plasmids ampicillin -amp cells Water bath to heat shock cells A freezer to incubate cells Process Step 1: Wash hands and sanitize lab setting. This will prevent anything reacting with a

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

of this lab was to compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme was present

Your first lab link can be found at Case One: Rookie Training. 1. What are the four basic steps of DNA processing? The four basic steps of DNA processing are extract‚ amplify‚ separate‚ and analyze. 2. From the toxicology lab‚ what is vitreous humor? Why do forensic scientists use it? Vitreous humor is the clear liquid inside the eye that gives the eye its shape‚ forensic scientists use this to confirm results received from the blood or urine. 3. From the survey in the toxicology lab‚ would you
