Version 42-0054-00-03 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. A change in temperature, such as the normal functioning of enzymes at 37 degrees C to a decreased or non functioning enzyme activity as the body temperature rises with a fever. More importantly, students can manipulate the models and easily discover complex properties of many biological and ecological systems. A change in pH, such as changes from an acidic environment of the stomach to the alkaline environment of the small intestine, in activates pepsin, a stomach enzyme used to digest proteins. Each sample will be identified as testing positive or negative. Did your results in Data Table 3 agree with or disagree with your expectations for the optimal pH? Enzymes are specific for the substrate in the chemical reaction.

Lactase catalyzes this process by reducing the amount of energy needed for hydrolysis to occur. The teacher can color a square with the color corresponding to the test strip key. Students will need to identify each sample as either being positive or negative and record results on the lab report. Using computational models allows users to interact with the quantities of a system, perturb the system, and use the model to understand the dynamics. For example, computational models allow students to manipulate systems that have: Students can explore these ideas with computational models. However, quantitative modeling allows students to interact with complex mathematical relationships without needing to understand all the math.

Most chemical reactions involving physiological processes in living organisms require an enzyme. Each group will share their answers in a whole class discussion. Foods to avoid would include: milk, soft not aged cheeses such as cream cheese and cottage cheese, yogurt, butter, and ice cream. If results do not match the answer given on the slide, students will retest the sample and correct the lab report. The teacher will tell class that the lab will explore the cause of stomach problems in certain individuals when consuming milk or milk products. Anyone can view it with the link below: You and the people listed below can view or edit. Use the data in Data Table 1 to support your answer.

Hypothesize how the structure of the lactase relates to the results in Data Table 3. Hypothesize how the structure of the lactase relates to the results in Data Table 2. You and the person listed below can view or edit. . Lactase functions best within limited ranges of both temperature and pH in its given environment, making it dependent on both factors for it to perform this essential reaction.

Students will compare and adjust their drawings on the lab report. Use the results in Data Table 3 to support your answer. In the body, the lactase enzyme functions to break down lactose during digestion. Deviations in pH outside of this range, particularly to the high basic levels of 10 to 12, can cause the lactase enzymes to become denatured. The teacher can supply examples for each end of the spectrum, lactose intolerance to Tay-Sachs. Lactase functions best between roughly 70 and 120 degrees Fahrenheit, or somewhere near or just above room temperature, with its function optimized at around 115 degrees Fahrenheit. Did the lactase enzyme show specificity? The continued production of lactase beyond infancy and weaning is a mutation.

Those below are considered acidic while those above are deemed basic. Only you can view and edit. This will not affect the results but will decrease cost and increase the amount of testing material. Explain why a glucose test strip may be used to determine the enzymatic activity of lactase. When the lactase enzyme is in short supply or not functioning, the body cannot effectively digest the lactose carbohydrate, meaning that the body has become lactose intolerant.

Since these reactions occur at the molecular level within the body, students do not directly observe enzymes functioning. They will write the results on the lab worksheet data table. Glucose test strips may be used to determine the enzymatic activity of lactase because they are being used to see the level B. Describe the relationship between pH and the enzymatic activity of lactase. The teacher will show slide with the reaction between lactase and milk. If lactase is rendered nonfunctional because of temperature or pH extremes, the breakdown of lactose stops. The environmental and cultural selective pressures that gave our lactose tolerant ancestors an adaptive advantage resulted in natural selection and ultimately the evolution of lactose tolerance throughout life.

Of those reactions, two were negative controls and one was a positive control. Our world is complex, and students need methods to experiment with these complex behaviors. Well Plate Contents Glucose Concentration 1 3 drops pH 3. Students will be given two samples of milk, samples A and B. A genetic mutation in Tay-Sachs causes the enzyme for lipid metabolism to function inefficiently. The teacher will grade the analysis section of the lab report. They do have to understand feedback loops, thresholds, and other important behaviors of systems.

Neither you, nor the coeditors you shared it with will be able to recover it again. In this exercise, five reactions were performed. In a computational model, the parts are not simply linked by variable x affecting variable y. Representing those systems with algebra is extremely daunting for high school students. When the entire class has recorded their results from testing each sample, the teacher will show a slide with the results.

They will be told that one sample has had lactase, an enzyme, added and one sample is untreated milk with no lactase added. Students should be able to identify that the results will vary from problematic but having a solution to fatal. The chemical reaction on which that enzyme worked would not occur at all or not in a time frame rapid enough to support the physiological process. Computational models are thought experiments run on a computer.
