Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we

faster and wide reaching. From inventions such as the six-hundred-year-old printing press to the Facebook and Twitter of today‚ media-based technology has never wavered in its role of expediting communication and opening doors. Social media is the catalyst that society needs in order to move forward. History is riddled with almost constant rebellion and change. Humans are simply not content with standing still‚ but they alone are incapable of achieving change at the rate and the scale at which is

The Mexican-American War served as catalyst that channeled the divisions between the North and South and the division within the political parties. The war was fought over American expansion near Mexican territory‚ which created major tensions that resulted in full blown war in 1846. The war was very controversial because it raised sectional tensions between the different regions within the United States. Many in the North were opposed to the war because they believed it was being fought to expand

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

Elizabeth Au (1) Serena Chan (3) Sharon Chan (4) Christy Chan (5) BIOLOGY LAB REPORT Investigation of the effect of metal ions 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

Vladimir Lenin: A Catalyst for Revolution In the late 19th and early 20th centuries‚ revolutionary Vladimir Lenin was the driving force behind Russian Marxism‚ reformation and organization of the working class‚ and the political catalyst behind the Revolution of 1905. During this time period‚ the new Russian working class had left the countryside for urban factories. Workers revolted against Tsarist oppression and participated in illegal strikes. Lenin organized workers under the Social Democratic

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

The expression "behind every man‚ there is a woman‚" rings true even in the Shakespearean tragedy Macbeth. Lady Macbeth is the catalyst that ignites the fire to Macbeth’s ambition. It is because she challenges his masculinity‚ questions his love‚ and belittles his bravery that Macbeth murders Duncan. His lady provides impetus for him to abandon all honorable nature in order to achieve what they both desire. Macbeth would not have murdered Duncan and continued on a downward spiral of evil were it
