In lab 4 you are exploring two enzymes, catalase that breaks down hydrogen peroxide into water and oxygen, and amylase that aids in starch digestion. These are two examples of the many enzymes found inside our bodies.

Enzymes are also used in many of the products we use! Check your cleaning supplies at home, do any of them list enzymes on the ingredient list? If so, does it say which type of enzyme? Any other products you use contain enzymes? What type of enzymes are used in industry? Which enzymes are found in the food we eat?

After doing some research, choose and describe one enzyme that is used in cleaning products, other products, industrial procedures or that is found in food. Explain how this enzyme is used. What is the substrate in the chemical reaction? And what is the product(s)?

Remember that a chemical reaction converts one or more substrates to one or more products, and that most enzymes are substrate specific. When looking for enzymes remember that their names end with -ase!

You main response should be at least 150 words and include references to all information sources used.

You also need to post at least one 100+ word reply to one of the other students’ posts. As part of your reply search for and share a video, tutorial or web-site that helps you and your classmates’ better understand enzymes.

Choose and research a topic related to human biology. Imagine that you are creating a small booklet that will become available at a local health clinic.

Written Assignment 2: Informational Booklet

Addresses course outcome 4:

  • weigh and make health-related decisions based on an understanding of the value and limits of scientific knowledge and the scientific method

Choose and research a topic related to human biology. Imagine that you are creating a small booklet that will become available at a local health clinic. The booklet should be educational and understandable by the general public. You may select one topic that relates to a disease that may interest you because of your own health or family history. Your paper should be at least 4 pages (double-spaced) long. This does not include references or any figures.

Topic

  • Disease: Hypertension.

Assignment criteria

  1. Select one of the suggested topics above (you may also choose a topic not listed above).
  2. Find articles related to the topic. You can find assistance with searching for articles at the UMUC Library Subject Guides at http://libguides.umuc.edu/science.
  3. Remember that this is a booklet. Write about 4 pages (double-spaced), excluding references and figures. You may include pictures, tables and other material but please include all references. You should cite information in the text from at least five sources (including books, journals, and the Internet). You may not use online encyclopedias as a source more than once. Use APA style for citing references (see http://www.umuc.edu/library/guides/apa.html). All source material should be paraphrased or summarized in your own words. You should have no more than one direct short quote (less than 40 words) and no long quotes (more than 40 words) in your booklet.
  4. The sections of your booklet should include a title; an introduction that defines/describes your topic and what current/ongoing research has discovered about this topic; backgroundinformation on what healthy organ system(s) is/are affected by the topic; the mechanism of action (e.g., how does the topic disrupt homeostasis? how does a disease spread and infect a person?); its symptoms and how it is diagnosed; current treatmentoptions; and your references. You may include additional sections as necessary to cover your particular topic.
  5. Please keep in mind that the audience for your informational booklet is the general public. Your explanations and uses of evidence, illustrations, or other definitive details should be appropriate for the reader; your language should aid the reader’s understanding of the subject (including definitions where appropriate); you should use information logically, and provide conflicting evidence and research where appropriate.

Assignment #2

U.S. Freshwater Use

In 2010, the population of the United States was approximately 309 million. According to the U.S. Geological Survey (USGS), the U.S. withdrew about a TOTAL of 355 billion gallons of freshwater per day for a variety of uses, and average per capita use was 1,150 gallons per day. Of that freshwater, 78% was from surface water withdrawals and 21% was from groundwater withdrawals. Read the 2-page USGS article (http://pubs.usgs.gov/fs/2014/3109/) and complete the assignment.

· Thermoelectric power plants (electricity) accounted for 45% of the total withdrawals

· Irrigation (of crops) accounted for 33%

· Public water supply accounted for 12%, and

· Industrial, livestock, and mining accounted for 10%

Use the information provided to complete this table (4 pts). Then answer the 2 questions.
