BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site is

chlorine bleaches. Now bleach - in scientific terms - is a kind of catalyst. A catalyst is a chemical that increases the reaction rate of a chemical reaction (catalyse)‚ and the chemical reaction involves enzymes. So to understand how bleach works‚ we first understand how enzymes work. Enzymes Enzymes are the most important thing in our lives‚ it makes the world go ‘round! Enzymes are proteins that acts as catalysts and help combine or break down hydrogen peroxide. Imagine a pen with

Catalysts in the Women’s Suffrage Movement There were particular women who worked tirelessly throughout their lives to obtain the right for women to vote‚ and they became some of the most important catalysts involved in the fight for the women’s suffrage from 1848 to 1920. Alice Paul was an American suffragist‚ women’s rights activist‚ and the main leader of the campaign for the Nineteenth Amendment which was ratified in 1920. Susan B. Anthony and Elizabeth Cady Stanton were earlier social reformers

Abstract Enzyme catalysis was observed in order to analyze how changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly‚ decreases‚ and levels off or completely stops‚ and can be further affected by environmental factors

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

Biological Psychology Biology is the study of all living things whereas psychology deals with the way these living things behave and react to external and internal stimuli. Biological psychology is the study of how a person’s psyche or behavioral characteristics are influenced by biological reasons found inside the brain or central nervous system. Understanding of this field relies on extensive knowledge of the functioning of the brain and nervous system and of difference psychological disorders

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get
