Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

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
