Can this effect be overcome when the temperature rises?ĭata Table 3: Glucose in wells a-d indicates enzyme activity at various pH levelsĪ. Explain what happens as far as the effectiveness of the enzyme at the freezing temperature. Based on your experiment results, what is the optimal temperature for lactase function?ĭ. What happens when an enzyme is boiled? Is this effect reversible?Ĭ. Graph the effect of temperature on the activity of the enzyme lactase.ī. Explain the experimental conditions for the five different wells.ĭata Table 2: Presence of glucose in wells indicating lactase activity at various temperaturesĪ. Explain why testing for glucose is used to determine the activity of the enzyme lactase.ĭ. Which of the wells showed a positive result for glucose? Explain the results.Ĭ. What determines a person’s ability to digest lactose?ī. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.Ī. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. Measure 2 cm from one edge for the first dot and then add a dot every 2 cm across the line. The sum of the genotypic numbers (BB + Bb + bb) should equal the total number of individuals in the population.0Enzymes: Temperature, pH, and Specificity Cut a piece of chromatography paper and using a ruler and pencil, draw a faint line 1.5 cm from the bottom across the entire width of the paper. Record the value in Data Table 4 in the first row under the column headings “Allelic Number” and “b.” n. This may be thought of as the total number of white beans pulled from the cup. Record the value in Data Table 4, in the first row under the column headings “Allelic Number” and “B.” m.Also determine the total number of b alleles. The number of B alleles may be calculated by multiplying the genotypic number of BB times 2 and adding the genotypic number of Bb. This may be thought of as the total number of brown beans pulled from the cup. For example, if you determined 22 individuals had the genotype BB, 22 would be recorded for Generation 1 under the column headings “Genotypic Number” and “BB.” l. Record the number of individuals with each genotype in Data Table 4 of your Lab Report Assistant. These values are the genotypic numbers for generation 1. For example, if a student has excellent lab reports, one can expect similar quiz grades and vice versa. Once hash marks have been recorded for 50 individuals, determine the total number of each of the 3 genotypes. Faculty appreciate using the LabPaq kits because they know that grading is more consistent as all students have a level playing field, and they can use lab reports as another way to ensure that students are achieving the course outcomes. Ensure that the beans are returned to the cup after each selection. Continue drawing 2 beans at a time until you have recorded genotypes for 50 individuals. Make sure beans are put back into cup after every selection. Continue to do this until 50 individuals are recorded. Record tally marks next to the appropriate genotype. Close your eyes and withdraw 2 alleles (2 beans) from the sample population. On a separate sheet of paper, record “BB,” “Bb,” and “bb.” This will act as a tally sheet for recording genotypes encountered in the population. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Record the expected genotypic numbers in the second row of Data Table 3. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report.
