Enzymes are catalytic proteins that speed up chemical reactions by lowering the activation energy of the reaction. our body cells depend highly on enzymes to complete many important functions‚ such as digestion and metabolism. Enzymes are selective‚ in which each enzyme can only speed up a specific reaction. There are molecules that enzymes work with called substrates. substrate bind to an area of an enzyme called active site. There is specificity between the enzyme and substrate that react with

HINTS ON WRITING YOUR REPORT Title: Enzyme activity Objective: To investigate the effect of temperature on amylase activity Design principle Background: Amylase activity products? (show the equation) Which factors will affect enzyme activity? How to study the rate of reaction? (e.g. rate of disappearance of substrates or rate of formation of products) Independent variable: temperature of reaction mixture or at which the enzymatic reaction occurs. It can be varied by setting water bath at

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

Lab 4 Quiz 1. Enzymes and what is their function? a. Enzyme: biological catalysts that regulate chemical reactions that occur in cells. Responsible for things such as converting food to energy‚ replace old damaged tissues‚ disposal of cellular waste products. Are responsible for lowering the activation energy. 2. Most enzymes are proteins with three-dimensional shapes determined by their amino acid sequence. 3. Substrate – is a reactant molecule that binds to the highly specific active site

Women of the 18 century and Today Rodney Pittman Grantham University Women of the 18 century and Today The Scientific Revolution which occurred in the years 1550 to 1700‚ introduced the idea that the universe and everything in it worked accordingly to the laws of nature which were discovered by means of reason. The reasoning was straying away from previous thinking which entailed that God was the creator of the universe and had complete control over individual lives. Women have always

Before the Scientific Revolution‚ the Bible or Greek philosophers such as Aristotle or as-tronomers like Claudius Ptolemy‚ whose ideas were sanctioned by the church‚ answered any questions regarding the natural world. In the bible it writes‚ "Mankind is the most important of God’s creations and occupies the centre of his universe." Astronomers there-fore stated that‚ "The earth is at the centre of the universe. The sun‚ the moon and the stars all move around the earth." During the scientific revolution

Enzymes are proteins or nucleic acids that catalyze reactions. They are able to speed up reactions by reducing the activation energy of a reaction. Each kind of enzyme has a specific shape that matches its substrate so it can bind to its active site. Enzymes convert their substrates into a product. Enzyme activity are affected by factors such as temperature‚ pH‚ and time. If an enzyme is exposed to extreme heat‚ it will become denatured‚ that is‚ to become deformed and lose its original shape which
Premium Enzyme Catalysis Chemical reaction
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

Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme‚ interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide‚ 3% H2O2 solution‚ swabs. Micrococcus luteus‚ Enterococcus faecalis‚ patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2. Watch for bubbling as an indication of
