This lab investigates the affect of sucrose on mitosis in onion root cells. The results of the experiment do not support the hypothesis. As the concentration of sucrose increases, the percent change in root length of the onion decreases. The individual data shows a 44.75% increase in the length of the onion root for the control group (0.0M). This is the highest percent change in onion root length. The solution is likely hypotonic. This means that it contains a higher concentration of water…

The FTIR spectra of four phosphazenium salts and P5+ are shown in Figure S1. Four phosphazenium salts have characteristic absorptions at 2850 and 2930 cm-1, belonging to the stretching vibration of -CH2- and -CH-, respectively, and this peak in the P5+ represents the absorption of –CH3. All the five compounds exhibit absorption at 960, 1230, and 1442 cm-1 corresponding to the stretching vibrations of P–N. In the FTIR spectrum of Cy4P1+BF4-, the peaks at 1633 and 3432 cm-1 belong to water because…

Discussion Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…

The Reaction of a food dye with bleach Introduction The overall purpose of the experiment was to determine the order in respect to the blue dye and the rate constant (K). With these found however, the overall rate law in the reaction between blue food coloring and the bleaching agent within commercial Clorox can be found. The orders in a rate law equation represent the relationship between the concentration of a given element or molecule and the overall rate, for example, when a reaction in…

We applied the thermodynamic model developed in this research to compare the equilibrium and experimental mole fraction of the product gases obtained from different bed materials. Figure 5 illustrates the evolution of the experimental mole fraction of the product gases for various bed materials. Also, a horizontal line indicates equilibrium mole fractions estimated by the thermodynamic model. It must be pointed out that the estimated equilibrium mole fractions of the product gases are expressed…

Data Analysis Does microwave radiation increase the speed the plant is growing? There were more than one variable. The independent variable is the amount of microwave radiation the seed received. The control group is non-microwavable seed, which was cell #1. The experimental group is microwaved seeds. Cell #2 was put in the microwave for 15 seconds. Cell #3 was put in the microwave for 30 seconds.The dependent variable is the amount of the plant growth. The control groups are the amount of…

The Effect of pH on Sucrase Kase Fears, Julia PaskVan, Austin Shead, Kylie Bonham, Haley Finkenbinder Introduction: Enzymes are proteins that function as catalysts. Catalysts speed up reactions by bringing substrates together into a precise orientation. The enzyme that will be tested is sucrase. Sucrase is secreted within the small intestine which will be used to speed up hydrolysis reaction into the products glucose and fructose. Therefore, the pH within a solution of benedict’s reagent will…

An enzyme is a protein catalyst, whose basic function is to increase the rate of the reaction, meaning lowering the activation energy. Because the body creates enzymes to be as specific as possible, in order to prevent inefficiency and careless mistakes, most enzymes come in direct contact with only one substrate to produce products. Enzymes will work on creating substances until the reaction is complete or the particular enzyme is inactivated, which either means being destroyed & recycled or…

INTRODUCTION: The objective of this lab is to measure the activity of an enzyme and the effects of environment conditions on enzyme activity. Enzymes are catalysts; agents that speed up chemical reactions by lowering the activation energy required. This means that a catalyst helps reactions occur at a greater speed and lower temperature. For this lab report we focused on the enzyme Tyrosinase, Tyrosinase is an enzyme that produces melanin from the amino acid tyrosine. Three different reactions…

Enzymes are biological highly selective catalyst, greatly accelerating both the rate and specificity of metabolic chemical reactions, from the digestion of food to the synthesis of DNA. Enzymes catalyze chemical reactions involving the substrate. Substrate is a molecule that attach to the active site of the enzyme protein which an enzyme acts. Active site is a small port in an enzyme that helps enzyme to bind with substrates and undergo a chemical reaction. During this binding of substrates with…
