o The 6 page research paper will cover a specific
protein molecule. The protein topics will be randomly distributed by
the instructor on the second or third day of class. (NOTE: The 6 page
minimum does not include the title page or references). Students are
encouraged to discuss their research papers with the instructor outside of
class.
o The paper will include the following components:
1. An overview of the protein molecule in terms of its presence in
different organisms, the functional and/or structural role of the protein,
the cells or tissues that express the protein in the organism, unique
structural components of the molecule, its role in aspects of
metabolism within organisms, and its interaction with other molecules.
(30 points)
2. Discussions of the experimental findings of the primary reference
papers. A brief discussion of the hypothesis of the experiments, an
overview of the techniques used to test the hypothesis, and the
experimental results from the papers should be included. (30 points)
3. A summary discussion of the protein molecule should conclude your
paper. This area should display an understanding of all relevant
information summarized from the research papers, including features
of primary through quaternary structure, co-factors, major
evolutionary adaptations, and roles for mutated forms of the protein in
diseases. You should include an evaluation of the phylogenetic profile
of this molecule – How many different organisms share this protein? it a member of a larger protein family? Is it essential to specific cell
functions? (30 points)
4. Research Paper Format: The 6 page report is to be typed (double-
spaced) with a 12-pitch Times New Roman font (no larger, no
smaller). All margins should be set at one (1) inch and fully justified
(4 points). Failure to adhere to the formatting requirements will result
in point deduction.
o A minimum of three (3) primary sources (where the authors are the
people who did the research) are required. These and other references
should be indicated as references in your final paper (6 points for
appropriate references). The National Library of Medicine website will
give you free access to PubMed (www.nlm.nih,gov) where you can limit
your search to links to “free full text.”
o You may contact the College of Sciences and Technology (COST) Library
Liaison in the Asa H. Gordon Library for assistance with finding pertinent
information. The process by which you learn to acquire information will
be valuable in any class where a research paper or literature search is
required

Methodology:
Write narrative methods paragraphs describing the methods you have conducted for your independent experiment. Cite any sources you used to develop your method. As appropriate, add a paragraph describing how you will (or have) analyzed your data statistically. Cite a source for your statistical method.
That file is my summary about the experiment

Follow the steps given to attempt assignment on oxy hemoglobin curve
Step 1. Read the topic of oxyhemoglobin curve from ebook.
https://openstax.org/books/anatomy-and-physiology-2e/pages/22-1-organs-and-structures-of-the-respiratory-system
Step 2. Then watch the 7 minute video https://www.youtube.com/watch?v=wgSUdxrlO8Y
After following steps 1 to 2, answer the following four questions:
Where in the body does hemoglobin have more affinity for Oxygen? _________
Where in the body does hemoglobin have lesser affinity for Oxygen?_________
In which direction does the oxyhemoglobin curve shift during Bohr’s effect? Explain the reason for the shift in detail.
In which direction does the oxyhemoglobin curve shift in fetus? Why is it so? Explain
Step 3. Watch another video https://www.youtube.com/watch?v=57P2Gsdq7is and answer the following questions:
4. When the curve shifts towards right, it takes _______ concentration of Oxygen to reach 50% saturation. Thus, a right shift means a ______ affinity of oxygen and hemoglobin
5. When the curve shifts towards left, it takes _______ concentration of Oxygen to reach 50% saturation. Thus, a left shifts means a ______ affinity of oxygen and hemoglobin
6. List all the factors that shifts the oxyhemoglobin curve towards right.

You’ll be completing the section titled “Your Task” at the end of the case study document. They provide a table to fill out for one of the four drink brands covered in the case; I will want you to complete that table for all four of the drinks, and then answer the questions which follow in such a way that you discuss/compare the four drinks, rather than only focusing on one. The case says to work in groups but you will be doing this individually, so I want you to compare all four of the energy drinks you investigate (rather than choosing one of them as the case instructions imply).
The last item, labeled “Assessment” at the end, you will skip because it is for a group rather than an individual. The assignment is pretty straightforward but be sure and ask me if you have any questions.

High Elevation Adaptation
Adaptations to living at high elevation including metabolic rates, respiration rates and hemoglobin concentrations are shared by many indigenous communities. These traits are heritable, and passed on to the next generation. Athletes train at high elevations to reap the benefits of these adaptations, even short term. But, it makes some people sick – ever hear of altitude sickness? What’s up with that?
Research high elevation adaptations. Talk about why some athletes train in the clouds but some people can’t get out of bed when they visit a ski resort. Your focus should be on using evidence about the structure and function of the parts of the cardiovascular and respiratory systems that are affected.
You must use evidence from at least one outside reputable source in addition to your textbook.
