The Effect of Enzymes on Apple Juice Production Biology Period 6 Background Info The purpose of this experiment was to determine which enzyme or the combination of the two enzymes makes the most apple juice from applesauce. We did his by‚ mixing 10 drops of an enzyme (cellulose/pectinase/both) into a few tablespoons of applesauce. We then left the rest to nature‚ and watched the liquid funnel out for 10 minutes. Lastly‚ we recorded our data. The cell wall is a complicated

Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

shrimps (UNT Lab Manual‚ 2017). They normally inhabit fresh to partly salty water and feed on fish‚ carrion‚ plants‚ and detritus. Because they are completely aquatic‚ they rely on their gills for breathing‚ but can spend short periods of time out of the water if their gills will not dry. Like most crustaceans‚ they have a hard‚ calcified exoskeleton. The heart is located in the upper portion of the cephalothorax‚ which is located just in front of the first abdominal segment (UNT Lab Manual‚ 2017)

Determining the Concentration of an Unknown Solution Graph: The effect of concentration of CuS04 * 5H20 on transmittance. I solved for my unknown by plugging in “y” as my given transmittance value‚ which was 85.0. y = -278x + 100.12 .85 = -278x + 100.12 -99.27 = -278x X = .357M (concentration) The relationship between the transmittance values and the concentration is an indirect relationship. Whenever the concentration increases‚ the transmittance decreases. It can also be reversed

Analysis of a Chemical Reaction Purpose: To observe a chemical reaction and to use qualitative and quantitative evidence to identify this reaction from among four possibilities. Hypothesis: I think the result is going to produce water. I think this is going to happen because there is hydrogen and oxygen inNaHCO3. Materials: -Test tube clamp - 150 mm test tubes (2) - burner - retort stand - clay triangle - iron ring - crucible Procedure: Part A: 1. Add 0.5 g of NaHCO3

Observing a Single Chemical Reaction Qualitative vs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. The results of the experiments were determined through close examination and observation of both qualitative and quantitative elements of the changes that occurred when a blue crystal‚ Copper Chloride‚ reacted with aluminum

in Methionine and the strong pos. charge of Arginine‚ Methionine is eluted first. (c) Glu and Val (i) Glutamic acid and Valine. (ii) Glutamic acid will elute first. Acids with greater negative charges have a small pKa‚ and are subject to a larger effect from electrostatic forces than acids with more positive charges. Therefore organic acids elute in order of pKa size‚ starting with the smallest pKa values. Valine has a higher pKa than Glutamic acid‚ which means Glutamic acid is eluted off first due
