BIOLOGY OF ENERGY HOMEOSTASIS

Write a five page (body; double spaced) review of the topic Metabolic Syndromefrom a
public health biology perspective. In your review, include the
following:

  • Discuss the biological basis of energy homeostasis, including an introduction to your chosen focus area;
  • Discuss
    some of the recent (within five years) and current research on the
    focus area you chose, including study aim, methods, and results of the
    studies you discuss;
  • Explain
    the value and application of the above research findings to public
    health, citing the studies as needed, and providing some examples of how
    this information is or can be used in public health policy, programs,
    and practice.

BIOLOGY

Part 2: After completing the table you will have a basic understanding of these two complementary metabolic processes. Using what you have learned, and additional reference information, answer the following questions.
1.What is the name for the type of organisms that can use Photosynthesis to produce glucose? Provide specific examples.
2.What is the name for the type of organisms can use Aerobic Cellular Respiration to break down glucose to produce ATP? Provide specific examples.
3.If oxygen is lacking, how might cells meet their energy needs through fermentation? Explain and give some examples of cells that can do this.
4.Both photosynthesis and aerobic cellular respiration are examples of complex metabolic pathways, consisting of many linked reactions. Briefly, explain the role of enzymes in catalyzing chemical reactions and in metabolic pathways.
Be sure to list and cite in APA, all references used to prepare both parts of this IP assignment.

a. Which organisms are most closely related? On what did you base your answer?
b. DNA from which organisms will probably hybridize?
3. One of the advantages of some newly developed rapid identification tools is that pure cultures aren’t needed. Why is a pure culture necessary for biochemical tests such as the Enterotube, but not for DNA probes?
4) Discuss the use of Bergey’s Manual as a tool of (1) classification and (2) identification.
5) Provide a reason to classify bacteria.
6) Bacteroides and Escherichia are both gram-negative rods found in the large intestine. Why are they in different phyla?
7) Provide an explanation for the complex life cycles exhibited by parasitic helminths. Cite specific examples in your discussion.
8) Explain how the presence of algae can indicate either pollution or productivity of a body of water.
9) Bacteriophages are used as vectors in genetic engineering to insert new genes into bacteria. Describe the process that makes this genetic recombination possible.
10) Compare and contrast the lytic cycle of infection of a DNA virus and an RNA virus.
11) Why was it previously believed that only DNA viruses could cause cancer? How can RNA viruses cause cancer?
12) You are growing Bacillus subtilis in nine 16,000-liter fermenters to produce enzymes…

BIOLOGY UNIT 3 DB

Assignment Type: Discussion Board Deliverable Length: 3-4 paragraphs
Points Possible: 70 Due Date: 5/18/2008 11:59:59 PM CTBiotechnology allows us to use living organisms or their processes for human needs or purposes. This current topic includes such examples as cloning, stem cells (adult, umbilical cord, and embryonic), DNA fingerprinting, biological warfare, bioremediation, genetically modified organisms, vaccines, and transgenic plants and animals to name a few.
Research how biotechnology is used today and answer the following questions:
1. What biotechnology application did you choose?
2. Briefly describe this process or application.
3. What benefits are derived from this?
4. Are there any concerns or negative impacts associated with this use of biotechnology? Why or why not?
