enzyme-catalyzed reactions. Introduction Living organisms are maintained by a complex system of biochemical reactions. Nearly all of these reactions require the assistance of enzymes. Enzymes are proteins that are capable of speeding up specific chemical reactions by lowering the amount of energy needed to start the reaction. A substrate is necessary to activate an enzyme, and does so by attaching itself to a specific site on the enzyme.

The focal point of the experiments that were conducted on the potatoes was enzyme’s activity under different conditions. Enzymes are proteins that help to speed up chemical reactions. They help to speed up these reactions by decreasing the activation energy for these reactions to occur. Enzymes work at very specific pH and temperature. This is because outside of their optimal range for these two conditions enzymes begin to denature, or change shape. Should an enzyme denature they will no longer function

Determining the Ksp value for silver acetate. Introduction: An equilibrium constant for a solid substance that is dissolving in an aqueous solution is represented by the solubility product constant, where the concentrations of different ions from the solid substance (compound) are used to calculate the solubility product constant. If the solubility product constant vale is high then the substance is very soluble in an aqueous solution. The solubility product constant is denoted by Ksp, and for

Investigating Enzyme Lab Hyeonjeong Lee 11B Research Question: How will the different temperatures (10℃, 20℃, 30℃, 40℃ and 50℃) effect on the rate of enzyme reaction? Introduction: • Enzymes are biological catalysts that act to boost up the rate of reactions. I am going to experiment the effect of temperature on the rate of enzyme reaction. Therefore, I am going to find out the temperature where enzymes activity is the most and least active. For this experiment, I am going to use computer simulation

The Effect of Different Concentrations of the Enzyme Catechol Oxidase on the Rate of Benzoquinone Production When Mixed with Pure Catechol Carson Levine November 4th, 2013 Abstract Catechol oxidase is an enzyme that speeds up the oxidation reaction when catechol is exposed to oxygen. When the reaction occurs, benzoquinone is produced turning the oxidized substance brown. It was hypothesized that the higher the concentration of catechol oxidase, the browner the

After completion of the transesterification reaction employed at the optimal conditions, the catalyst was collected from the reactant mixture by filtration; the catalyst was washed with hexane several times to remove the adhered oil particles, and then dried at 110°C for 2 hr. The catalyst was reused several times without further treatment to obtain FAME from WCSO. To evaluate catalyst stability, the optimum amount of CaO that was obtained by examining the operating condition was stirred with 38ml

of light a chemical can absorb. In our findings we discovered that certain environmental factors such as pH, temperature, boiling do have an affect on enzyme activity. In conclusion the five null hypothesis were proven to be incorrect. Introduction Enzymes are biological catalysts that carry thousands of chemical reactions that occur in living cells. They could be found in every living thing. Enzymes increase the rate at which chemical reactions occur. A catalyst speeds up a chemical reaction by

Living organisms must undergo chemical reactions of cellular metabolism to maintain life. This process is performed with the help of the active site found on the enzyme. The active site is sensible to changes that are made to the enzyme, so when a factor that affects the enzyme is present, the reaction rate will be affected. In this experiment the effects of enzyme concentrations, substrate concentrations, temperature concentrations and adding an inhibitor on the enzyme’s reaction rate will be tested

substrate and enzyme concentration on reaction rate in which the effects were tested with three concentrations of both enzyme and substrate (low, medium, and high).After properly setting up the spectrophotometer in addition to calibration and adding chemicals into the control, enzyme and substrate, one should mix all three concentrations of low, medium, and

Enzymes are defined as catalysts that speed up chemical reactions but remain the same themselves. The shape of an enzyme enables it to receive one type of molecule and that specific molecule will fit into the enzyme’s shape. Where a substance fits into an enzyme is called the active site and the substance that fits into the active site is called a substrate. Several factors affect enzymes and the rate of their reactions. Temperature, pH, enzyme concentration, substrate concentration, and the presence
