Temperature is a measure of kinetic energy. As this movement increases‚ collision rate and intensity‚ and therefore reaction rates‚ increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction rates until proteins denature. Introduction Enzymes combine with reactant molecules (substrate) and

Experiments described were performed by me and/or my lab group and this write-up is entirely my own creative work.” X________________________________________ Introduction Enzymes are protein molecules that speed up the rate of reactions by reducing the activation energy of a reaction. They act as catalysts in reactions‚ increasing the rate at which

Purpose Determine which kinds of reactions involve electron transfer as the driving force. Background Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed. So‚ when a metal and a nonmetal react‚ there is an ionic bond formed‚ which means one of them loses electrons while the other gains them. Since this reaction involves the exchange of electrons it is termed as a redox reaction. The oxidation states in a metal- nonmetal are simple

1: INTRODUCTION When studying the function of catalysts in reactions during the kinetics unit‚ I was eager to know more about the position of enzymes‚ which function as biological catalysts in biological systems. After doing some further research‚ I found that catalase‚ an enzyme‚ which is found in nearly all living organisms such as animals‚ catalyses the decomposition of hydrogen peroxide (H2O2) in the blood. H2O2 is produced by reactions in the white blood cells in our body to fight against diseases

The Outsiders‚ elucidates that friendship becomes the most vital value in a world where parental influence is scarce and violence seems to be the only answer. Constantly in conflict are the two social groups known as the Socs‚ the rich and privileged‚ and the Greasers‚ the poor ‘hoods’‚ yet both find common ground in the fact that friendship is immensely important . The depth of the friendship between Johnny and Ponyboy can only be explained with one word‚ unbreakable. Both boys confide in each

If pH > pI‚ then the protein will have a negative charge and if pH < pI‚ the protein will have a positive charge. Buffer I has a pH >5‚ meaning both proteins carry a negative charge and bind to the DEAE (a positively charged resin). (b) pH = pKa + log10(Base/Acid) [Base = mM of sodium acetate; Acid = mM of acetic acid] = 4.7 + log10 (40/40) = 4.7 In order for the catalase to elute from the column‚ it must have lost its negative charge and stopped binding to the DEAE. Lowering the pH

The purpose of this experiment was to synthesize triphenylmethanol from a Grignard reagent. The Grignard reaction technique was used in this synthesis but due to the fact that it is such a strong nucleophile and base‚ it was important to prevent water from interfering with the Grignard reaction. Purity of the product was determined by measuring the melting point. Reagent Table: Structure Name Molecular formula Molar mass Density Melting point Boiling Point Diethyl ether C4H10O

All the Troubles in the World vs. Minority Report The two computers “All the Troubles in the World” and “Minority Report” are both machines that can predict the future‚ but they operate in different ways. The computer in Minority Report is actually 3 human beings with psychic powers. However the computer in “All the Troubles in the World” is actually a super computer that becomes so complex it starts to act like a human. Some other differences are that Multivac controls the world’s economy and
