    Effects of Different pH Solutions on Lactase. Caitlin Hathaway, 2016, Functional Biology, Texas State University, San Marcos, TX, 78666. Enzymes work at different rates in different environments. We investigated the relationship between pH levels and the ability for the lactase enzyme to catalyze reactions. Lactase was added to different levels of pH with substrate and their subsequent rates of catalysis were measured. Out of the four samples, the experiment showed that the lactase was most efficient in pH 8, the least in pH 2 and 4, and was rather efficient in pH 10. We concluded that pH does have an effect on the efficiency of which an enzyme can catalyze substrates. Enzymes are one of the most important things in our bodies, catalyzing…

  • Lactase Lab

    Introduction: Lactase is an enzyme that helps to digest lactose, a sugar found in many dairy products (U.S National Library of Medicine 2013). This enzyme is made through instructions provided by the LCT gene. Lactase is primarily produced and found in the cells that line the walls of the small intestine. At the brush border, an area where microvilli absorb nutrients from food as it passes by, lactose breaks down lactose into simpler sugars like glucose through a hydrolysis reaction (Biology…

  • Monosaccharide Lab Report

    In this case, we added the lactase solution (independent variable) to milk. The dependent variable of this experiment was milk. In this case, the amount of glucose produced in the milk (dependent variable) was measured. The constants of this experiment were the amounts of liquids (10 mL of milk and 1 mL of lactase), time to break down before testing (6 minutes), temperature, and type of container (test tube). The purpose of the experiment was to test the effect of the enzyme lactase on the milk…

  • Single Nucleotide Polymerase Gene Study

    polymorphisms in the human lactase phlorizin-hydrolase gene have been associated with the ability of certain individuals to constantly digest milk products. These mutations in the lactase gene lead to constitutive expression of lactase, which is then used to break disaccharide lactose into glucose and galactose constantly throughout adulthood as lactase persistence. In particular, past research has shown that some individuals of the African and European descent have been found to have single…

  • Lactose Intolerance

    Between thirty to fifty million Americans are considered to be lactose intolerant. Lactose intolerance is a common chronic digestive disorder in which a person’s intestinal tract lacks the ability to make lactase. It results from a drop in or disruption of the production of lactase in the small intestine. The small intestine is a primary part of the digestive system, and is the longest part of the gastrointestinal tract and makes up about three quarters of the digestive system. It is a hollow…

  • Lactose Intolerance Essay

    type is when the person produces lactase in the beginning of their life but then their production of lactase diminishes, which makes milk hard for the body to digest (Diseases and Conditions: Lactose Intolerance). Secondary lactose intolerance occurs “when your small intestine decreases lactase production after an illness, injury or surgery involving your small intestine” (Diseases and Conditions: Lactose Intolerance). The illnesses that would cause this include Crohn’s and celiac disease…

  • Separation Of Glucose Synthesis Essay

    First Experiment- One lab partner should prepare a test tube that contains 10 mL of the lactose solution. Make sure to label the tube as being Tube One. Another lab partner should prepare a test tube with 10 mL of the lactose solution and 1 mL of the lactase solution. Take caution in measuring the solutions. Label the tube with lactase and lactose as being Tube Two and cut off an appropriate amount of paraffin wax paper to cover the opening of the tube. Press the paper tightly to the tub and…

  • Lactose Lab Report

    millions of people. People with this condition do not produce the lactase enzyme which metabolizes the sugar on their own therefore they are unable to break down the Lactose which is sugar that is found in milk. Lactase is an enzyme found specifically in milk sugar “Lactose”. It breaks down the lactose into monosaccharaides, galactose and glucose. The Lactase enzyme can be used to aid people with this condition. Saladin, K. (n.d.). ANATOMY & PHYSIOLOGY: THE UNITY OF FORM AND FUNCTION BUNDLE…

  • Investigating Chemical Reactions

    Coffactors Abstact Chemical reaction are a part of every ones life there no dening it this fact. But is there a way to increase these reations and make processed like reasperation and metablolism faster. That is exactly what cofactors are beleived to do, increasing the rate of reaction. In this experirment lactase, ONPG, EDTA, and phosphate buffer are used to determine wether or not cofactors really increase the rate of chemical reation. To measure the reaction a spectrometer will be used.…

    determinations are carried out somewhat below that temperature (McKinney, 2016). Nevertheless, direst study comparisons are often difficult because of the differences in the handling and processing of solutions prior and during the enzyme analysis, and because the influence of those differences on enzyme activities independent of its potential activity. Materials and Methods: During this lab, we determined how the change in temperature influenced the reaction rate of a lactase catalyzed…
