Link reaction The link reaction takes place in the mitochondrial matrix and its main function is to turn the pyruvate into acetate for the kerb cycle. During the link reaction the pyruvate molecule undergoes decarboxylation and dehydrogenation‚ the enzymes pyruvate decarboxylase and pyruvate dehydrogenase remove the carboxyl group (which becomes a carbon dioxide molecule) and removes the hydrogen atoms from the pyruvate molecule. The coenzyme NAD accepts the two hydrogen atoms and becomes reduced

Grignard Reaction: Synthesis of Triphenylmethanol Hai Liu TA: Ara Austin Mondays: 11:30-2:20 Abstract: In this experiment‚ phenylmagnesium bromide‚ a Grignard reagent was synthesized from bromobenzene and magnesium strips in a diethyl ether solvent. The Grignard reagent was then converted to triphenylmethanol‚ a tertiary alcohol with HCl. The reaction for phenylmagnesium bromide was: The reaction for Grignard to triphenylmethanol was: In the formation of the Grignard reagent

In this laboratory voltmeters where utilized to take reading of three different electrochemical reactions: Pb/Zn‚ Pb/Cu‚ and Zn/Cu. A salt bridge was placed between two reactions containing metal strips in separate aq solutions. The salt bridge was placed in order to balance the reaction. The voltage measurements for Pb/Zn‚ Pb/Cu‚ and Zn/Cu where .595 V‚ .479 V‚ and 1.072 V accordingly. The values obtained where then used to determine the voltage value for the reduction half. The resulting cell potential

NaHCO3 and NaCl and calculate a balanced equation for this reaction. Safety: • Wear safety goggles at all time • Handle all chemicals with care • Use equipment like tongs when handling warm/hot objects • If chemicals are spilt on self‚ wash off immediately • Stand at all times Hypothesis: The NaHCO3 will react successfully with the HCl and will form NaCl‚ H2O and CO2. Then be able to work out a balanced equation for the reaction and work out the moles of NaHCO3 and NaCl. Materials:

observe how the change in solvent polarity affects the rate and to determine the kinetics of a solvolysis reaction. In this experiment‚ we used 1-chloro-1-phenylethane in acetone in one reaction with 50% ethanol-50% water and in another reaction with 40% ethanol-60% water. To monitor he rate of reaction‚ we would need the concentration of the alkyl chloride at the beginning of the reaction and at a time t‚ but since we did not determine the concentrations‚ we monitored the rate of formation of

Abstract The experiment is to identify the guilty suspect that is present at the crime scene by comparing with the DNA samples. Polymerase Chain Reaction(PCR) is used to amplify the small amount of Deoxyribonucleic Acid (DNA) for forensic or genetic studies‚ which require necessary product and placed in the thermal cycle. Gel electrophoresis is being run in order to analyze and compare the DNA samples at the crime scene with the guilty suspects. Gel electrophoresis is used to separate DNA using

SHOPPING FOR A HOME Antonio Valdez Buying a home is a process that many of us will go through in our lifetime. If we are like many other prospective buyers‚ we will experience this major decision three or four times in our working years. A home is often the largest purchase we will make‚ and it therefore deserves our careful attention. “Many people think that the most important criterion in shopping for a home is its site.”1 The site should be on land that is well drained and free from flooding

organism used for this experiment was Saccharomyces cerevisiae (S. cerevisiae) which is often called baker’s yeast. S. cerevisiae has several characteristics that make it an ideal organism to use in experiments. S. cerevisiae is a single-celled eukaryote capable of reproducing through mitosis or sporulation. This means that the yeast has both a haploid and a diploid stage. In yeast‚ the haploid cells are n=16 and the diploid cells are 2n=32. S. cerevisiae has two haploid mating types MATɑ and MATa. When

Introduction The purpose of this experiment is to determine the rate equation for the “Iodine Clock Reaction” experiment. The experiment will consider the equations 〖2I〗^-+S_2 O_8→2〖〖SO〗_4〗^(2-)+I_2 and I_2+2〖S_2 O_3〗^(2-)→2I^-+S_4 O_6 in order to determine the rate law of Rate=k[〖〖S_2 O_8〗^(2-)]〗^a 〖[I^-]〗^b by using the experimental data to calculate the values of exponents a and b as well as the rate constant k. Experimental Supplies Needed: 250 mL Erlenmeyer flask‚ 100 mL beaker‚ graduated

The color change proved it was a chemical change. #2 The reaction turned yellow and it separated and created a fog. The solid formed precipitation and had a color change during the reaction proving it to be a chemical change. #3 There was green smoke and the crystals turned black. The green liquid turned dark green and continued to sizzle with
