001 Lab Performed 8th‚ 2012 Lab Report Submitted February 22nd‚ 2012 Abstract The purpose of the lab was to determine the order of reaction for the dye Red #40. By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach completion. By comparing two solutions of dye that have different concentrations‚ the

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

between the two extremes. The SN2 reaction occurs in a single step. The nucleophile simultaneously attaches to the substrate as the leaving group leaves. The reaction displays second-order kinetics; its rate is proportional to the concentrations of the both the substrate and the nucleophile. In a SN1 reaction‚ the first step is departure of the leaving group from the substrate to form a carbocation(rate-determing); the second step the carbocation rapidly attacked by a nucleophile.

was originally predicted. This may be because the bacteria are unable to convert squalane into squalene for use in the hopanoid biosynthesis pathway. Another possibility is that the bacteria are using other materials than squalane as a preferred substrate in this pathway‚ as they would require less energy to convert into the necessary compounds. Despite the lack of temperature-dependent effects‚ the consistent significant increase in growth in samples treated with squalane indicates that this compound

Yeast Fermentation Lab Report SBI4U Chaweewan. Sirakawin Present to Ms.Allinotte November 21. 2014 Introduction: Fermentation is a metabolic pathway that produce ATP molecules under anaerobic conditions (only undergoes glycolysis)‚ NAD+ is used directly in glycolysis to form ATP molecules‚ which is not as efficient as cellular respiration because only 2ATP molecules are formed during the glycolysis. One type of fermentation is alcohol fermentation‚ it produces

We take half the protein and add pancreatic enzyme a. This enyzme will hydrolyze the protein into its amino acid subunits a. This simulates how the hydrolytic process is carried out naturally‚ because in real life it is done with enyzmes! 1. And the other half of the protein

phosphate concentration‚ the substrate‚ on the enzyme‚ acid phosphatase‚ reaction. In an enzyme reaction‚ there is substrate that binds to the active site of the enzyme and product is the end result. The enzyme is the catalyst for the reaction which means that it speeds up the process. Without enzymes‚ the majority of reactions would not occur because the activation energy level would be unattainable. With this in mind‚ the hypothesis was that the RM4 solution‚ the one with the most substrate‚ would
