Science IA Rough Draft The Effect of Temperature on The Activity of The Enzyme Catalase Introductions: Enzmyes are proteins that catalyze chemical reactions. All living things have catalase present in them. Catalase is a common HYPERLINK "http://en.wikipedia.org/wiki/Enzyme" enzyme found in nearly all living organisms that are exposed to oxygen‚ where it HYPERLINK "http://en.wikipedia.org/wiki/Catalyst" catalyzes the decomposition of HYPERLINK "http://en.wikipedia.org/wiki/Hydrogen_peroxide"

Enzymes and Their Importance in Plants and Animals Enzymes are large proteins that are responsible for catalysing thousands of metabolic processes that sustain life. Enzymes work similarly to those catalysts used in industry by lowering activation energy and therefore dramatically speeding up the rate of a reaction‚ however‚ these biological catalysts are highly selective to their substrate. Almost every chemical reaction that occurs in a cell requires enzymes in order to occur at rates required

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

Factors Affecting Enzymes The activity of an Enzyme is affected by its environmental conditions. Changing these alter the rate of reaction caused by the enzyme. In nature‚ organisms adjust the conditions of their enzymes to produce an Optimum rate of reaction‚ where necessary‚ or they may have enzymes which adapted to function well in extreme conditions where they live.Increasing temperature increases the Kinetic Energy. In a fluid‚ this means that there are more random collisions between molecules

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

Concentration Camps Sydney Quarantillo Grand Island Senior High School “The Holocaust illustrates the consequences of prejudice‚ racism and stereotyping on a society. It forces us to examine the responsibilities of citizenship and confront the powerful Ratification’s of indifference and inaction” said Tim Holden. The holocaust is something worldwide that will never be forgotten and cannot be erased from history. To understand the holocaust learning about Adolf Hitler

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise
