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

on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive inhibitors. They do not compete with the substrates for the active sites of enzymes. They attach to other parts of the enzyme molecules

PS3240 Week 2 #4: Exploding the Powder Keg Myth (Preemptive wars almost never happen) Dan Reiter Important points • Existing argument: Preemption is most likely path to armed conflict (Int’l system as primed powder keg‚ waiting for single spark to explode into war) BUT these claims have not been matched by extensive empirical scholarship‚ has not been proven. Reiter’s Argument: • Empirical finding: preemptive wars almost never happen; in cases where they did happen‚ it was due to other

relationship between substrate concentration and initial reaction rate provided that substrate concentration is much greater than enzyme concentration. Enzymes are essential to life as they are required for many vital metabolic reactions to occur. To adequately explain the properties of enzymes‚ it is assumed that an enzyme-controlled reaction takes place through an enzyme-substrate complex by the lock and key mechanism. It is hypothesized that a greater concentration of product is achieved through

dreaded washing day (Pg. 70 Lines 1-8) Anna Letitia Barbauld’s poem “Washing Day” is categorized as mock epic. A mock epic is defined as: epic tone and form but for ‘ordinary’ subjects. Another example of a mock epic is Alexander Pope’s The Rape of the Lock (1712). This literary work stands out to me because while it is a mock epic‚ the first time I read it‚ I did not come to that conclusion.

Label five test tubes 1-5. Place 4 mL of 1 % starch in each of the first four test tubes. Place 4 mL of amylase solution in the fifth tube. Place all of the tubes in the 37°C water bath for 5 minutes. Obtain 5 clean droppers and label them 1-5. (To avoid contamination of these solutions

energy. They also remain unchanged after use‚ which enables it to be used repeatedly. Cells have special catalysts called enzymes‚ which are specialized proteins that help accelerate chemical cell reactions. (Evert‚ RF & Eichhorn‚ SE 2013). Enzymes also control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism

Enzymes are biological catalysts that operate at the temperatures‚ pressures‚ and moderate pH values found in living organisms. They help in a faster chemical reaction in our human body. Besides this‚ enzymes also play a huge role in various industries. The following paragraphs will talk about how various enzymes are used in various industries : The Dairy Industry and Medical Industry. In the dairy industry‚ the enzyme Protease is used widely. While making cheese‚ protease helps coagulate milk
