Enzymes are biological catalysts and each individual enzyme can only catalyse to one type of reaction – due to its specific shape. Each individual enzyme has its own specific shape which is determined by the amino acid sequence that it is made up of – each enzyme’s active site matches to its unique substrate molecule. For the sake of our experiment – enzymes catalyse reactions because they become an active site for reactions to take place. This lowers the energy that is needed for the reaction but

Determination of the activation energy of an enzyme catalysed reaction Introduction In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate‚ as well as the rate of reaction and the activation energy of p-nitrophenol phosphate. Enzymes are biological molecules that catalyse a chemical reaction. ‘Enzymes work by lowering the activation energy of a chemical reaction making it easier to proceed’ [1]. This allows molecules to have more energy therefore

Enzyme Reaction Rates Under Different Conditions Introduction In this lab you will observe how the rate of a reaction is changed as certain factors are changed. You will observe how changing factors like temperature‚ pH‚ substrate concentration‚ and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the

Enzyme Catalysis Lab: Laboratory Write Up Problem/Question: What happens to the amounts of gas produced in a catalyzed reaction of Hydrogen Peroxide when the catalyst is mixed with an acid? Theory/Hypothesis: In this experiment the researcher and their team will be performing tests on a catalyst (proteins found in potato) to see what will happen when the catalyst in a Hydrogen Peroxide reaction is treated with an acid before the reaction occurs. The researcher hypothesizes that the after treating

All living organism depend on catalytic proteins called enzymes‚ these compound are responsible for metabolism and biochemical regulation of energy‚ there are millions of enzymes and hundreds of enzymes have been identified in the human body as well. All living system possess enzymes as vital components of the body‚ enzymes are found in all organisms. Everyone has a natural pH balance in the body. Enzymes are complex proteins which speed up chemical reactions if this did not happen it would occur

Abstract: Enzymes are specific-type proteins that act as a catalyst by lowering the activation energy of a reaction. Each enzyme binds closely to the substrate; this greatly increases the reaction rate of the bounded substrate. Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2)

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol
