It is hypothesized that the optimum pH of trypsin is 8. Three different pH levels were tested, and each level consisted of three trials. The pH of 5 showed an average absorbance of 0.021±0.002, the pH of 8 showed an average absorbance of 0.167±0.030, and the pH of 11 showed an average absorbance of 0.088±0.001. Based on the standard deviation, there was a lack of variability between each trial for the pH levels of 5 and 11, yet the trials of the pH of 8 varied greatly compared to the other…

effect on the enzyme catalase, taken from a cut and blended potato. The blended potato mixture was strained and put into a centrifuge, the liquid that was in the centrifuge contained the enzyme and remained on ice. The enzyme was placed in test tubes that had varying levels of pH buffers, substrate concentrations and temperatures; the pH, substrate concentration and temperature were the three variables. The data showed that each variable contained an optimum level at which the enzyme was most…

Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme (Thompson, 2005). In the experiment completed, this is shown through the creation of O2.…

hydrogen peroxide solution (10°C, 20°C, 30°C, 40°C, 50°C, 60°C) This is used to determine the rate of the enzyme catalase reaction. Dependent Variable The dependent variable are the values, which depend of the independent variable. The height of the froth in the test tube when the liver cube is reacted with hydrogen peroxide. The height of the froth is determined by the rate of the of the enzyme catalase reaction at varying temperatures. Constant Variables A constant variable are variables…

BIOLOGY LAB REPORT. ENZYME ACTIVITY Planning (a) – Pl (a): Research Question: How does the concentration of the salivary amylase affect its activity? Aim: To investigate the effects of concentration on the activity of salivary amylase Hypothesis: The lower the concentration of the salivary amylase, the less the enzyme activity and vice-versa is true provided that other factors such as temperature and the pH are kept constant. Variables: Independent variables: • the concentration of…

Case Study 1: 1.The most likely cause of the ABO typing discrepancy in the reverse type is due to “unexpected antibodies” such as a cold/room temperature reacting alloantibody. 2.Since the auto control didn’t agglutinate, an alloantibody is suspected. With that being said, it needs to be one that reacts at room temperature. Furthermore, based on the antigen typing of the patient P1 is suspected to be interfering with the ABO results. The Lewis antigen was ruled out due to it being present on…

Results: Figure 1; Repellent activity in percentage of the volatile extract of C. sinensis, C. limon, C. aurantifolia and positive control on Camponotus nearcticus. The activity was generally high on C. nearcticus with positive control recording 100% activity, C. limon having 95% and C. sinensis having the lowest activity of 82.5% activity. Figure 2; Observed percentage lethal activity of the volatile extracts on C. nearcticus at five concentration points after 180 minutes of exposure…

1. Surrounding Temperature At Trader Joe’s and Ralphs, both the apples and bananas were found at room temperature, whereas the broccoli was refrigerated at both locations. Temperature is the most important factor affecting respiration. Within a certain range, most respiration rates are directly related to temperature. As temperature increases, so do the respiration rates. Apples and bananas are not refrigerated because they display similar respiration rates when chilled as opposed to room…

SKELETAL MUSCLE PROTIENS Acting:- • Contractile protein. • Consists of 2 alpha helical strands of g-acting molecules bond in succession. • Each g-acting has a required site where the s1 piece of the myosin cross-bridge multifaceted binds right through weight reduction. Myosin:- • Contractile protein. • Consists of two profound (shape tail constituency and two cross-bridges that disconnect with acting to produce force) and four light chains (that influence cross-bridge cycling kinetics and…

Chicken hybrid (Cobb 500 and Hubbard Classic) and dietary treatment (0.0%, 0.1% and 0.3% of L-histidine) did not affect (P > 0.05) live weight, carcass weight and weight of breast muscle. Chicken hybrid influenced weight of thighs with drumsticks (P < 0.01), weight of the back (P = 0.002) and weight of wings (P = 0.001). Dietary treatments affected weight of thighs with drumsticks (P = 0.007) and weight of wings (P = 0.006). Opposite to the results of this investigation, Nikolova et al.…
