Meerra Gandi‚ Erin Barody‚ Samantha Gutcho Title: The Effect of Adjusted Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase

Lab Report: Enzyme Lab Your Name: Samantha Butcher Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? It is going to explain how a liver’s enzymes break down substances that could be harmful.| Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. Give your reasons and outline any assumptions that lead

Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity:

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

Enzyme kinetics (catalase/kmno4) Enzyme catalysis Farah Mohamed galal 22-3014 t09 Introduction: E + S → ES → E + P Enzymes are proteins which act as a catalyst in biochemical reactions(affect the rate of achemical reaction). The substrate binds to the active site of the enzyme. Any deformation of the active site will affect the activity of the enzyme‚ these are some ways that enzyme action may be affected because of them: 1- Salt concentration: If it is close to zero or very high

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

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

Action of enzymes as catalysts in biochemical processes * Enzymes acts as catalyst and increase the rate of all the chemical reactions. * Enzymes are also described by two properties like all other catalysts. It composed of two main functions. * The first function is that‚ they increase the rate of chemical reactions by without consumed themselves or undergo any change or alteration in the reaction. . ( Zemitec et‚al 2008). * The second function is‚ they increase reaction rates
