    Use of Enzymes in Food Industry - Food industry utilizes a variety of enzymes for processing of various foods‚ e.g.‚ production of various types of syrups from starch or sucrose (a- and β-amylases‚ glucamylase‚ pullulanase‚ invertase‚ and glucose isomerase)‚ meat/protein processing using proteases‚ removal of glucose and or molecular oxygen (O2) using glucose oxidase and catalase‚ use of lactase in dairy industry and use of enzymes in fruit juice and brewing industries. Glucose oxides are obtained

    Purpose: To find how pH and temperature levels affect the enzyme Background: Enzymes are a type of protein vital to sustaining life‚ it works with vitamins and minerals as a biological catalyst‚ which lowers the activation energy for a reaction to occur. Each individual type of enzyme does a specific job‚ and they do not die‚ they are reused. For example‚ catalase is an enzyme found in almost all living cells that will break down hydrogen peroxide and turn it into water and oxygen. The

    Biology- Change in pH Aim: To investigate the affect that change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known

    Enzymes are catalysts that are used to speed up chemical reactions. Adding inorganic catalysts to reactants increase the rate of most chemical reactions. However‚ all enzymes are different and there are numerous amounts. Many enzymes are essential for life and reactions would not happen rapidly to maintain life with the help of enzymes. Specific enzymes lower the activation energy for specific reactions and shapes. Activation energy is required to start a chemical reaction. This occurs when energy

    Enzyme Catalysis Introduction: Enzymes are produced by living organisms as proteins. These enzymes perform as catalysts to bring about a chemical reaction. In fact‚ most reactions are catalyzed by enzymes during reactions in the cell or in the human body. A catalyst that enzymes pose ad are by definition substances that are capable of initiating or speeding up a chemical reaction. Catalyst are not a necessity during a chemical reaction‚ they are just used to speed up a chemical reaction. This event

    Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without

    was designed to investigate the effects of temperature on reactions between the enzyme catalase found in animal tissue with the substrate H2O2. The hypothesis stated that an increase in the temperature of the substrate would create a subsequent increase in the rate of reaction between the enzyme and the substrate. This hypothesis was tested by immersing 1cm cubes of animal tissue (sheep liver) which contained the enzyme catalase into the substrate (H2O2 ) mixed with detergent which foamed showing a
