CORE CURRICULUM ASSESSMENT AND ENZYME LAB QUIZ Spring 2019

Assessing: Communication, Critical Thinking and Quantitative Reasoning Skills



1. Refer to writing guidelines on Blackboard for requirements and sections of a report.


Be sure to state the purpose of running the peroxidase reaction at different environmental levels.


2. Submit a bar graph constructed on MS Excel showing the effect of pH on the reaction rate of

peroxidase from the data obtained in the laboratory.

 

3. In essay format, discuss the effect of pH or temperature on peroxidase’s ability to catalyze the reaction as evidenced by the results obtained in the lab.


a. The discussion shall include a quantitative analysis of the data and address these questions:

  • What assumptions did you make when analyzing and interpreting the linear plots obtained in the lab and used to construct the bar graphs?

  • Were the results consistent with what is known about how pH affects protein structure and why peroxidase structure is important to its function?

  • Was your hypothesis regarding the effect of pH falsified or supported?

  • Given the results you obtained, what do you think the results would look like if

1) more pH levels were tested (rather than just four)

2) peroxidase was extracted from potatoes instead of turnips

  • Given the results you obtained, how can you improve this experiment to obtain additional relevant data?



b. The discussion must include at least one properly formatted citation using published sources.


The Council of Science Editors (CSE) provides a variety of ways to cite your references.

In the citation-name system, number your sources alphabetically by each author's last name in the reference list at the end of your paper. In the sentences of your paper, cite these sources using the number from the reference list. This means that the in-text citation 1 or (1) refers to the first source in your alphabetical list.



Format for books citations: List all authors by last name and initials, separated by commas if there are more than two authors. Put an "and" before the last author in the list. Then put the year of publication, the title of the book (in italics if possible), the publisher, the city, and the number of pages in the book.

Format for scientific journal articles citations: List the author(s) of the article using the same format given above for books, then give the year, the title of the article or chapter (no quotes, italics or underlines), then the title of the journal or magazine (in italics if possible), the volume number of the journal (do not use the publication date), and page numbers where the article can be found.

Format for web citations: Author, A. A., & Author, B. B. (Date of publication). Title of article. Title of Online Periodical, volume number (issue number if available). Retrieved from http://www.someaddress.com/full/url/
