The “prion paper” is a collection of information about prions. This packet of information is for you to be able to apply many of the concepts we have covered thus far to a real-life situation- Prion diseases. All of the references are listed at the top of question sheet- some information is much more technical than others. There are also some additional references below that may help with your answers. There is information about viruses (online lecture and an excerpt from the big cell book if you want to read it).

What kinds of concepts? Protein folding, protein misfolding and degradation (or not), importance of secondary structure, hydrophobicity of amino acids/proteins, western blot, a reason to use monoclonal antibodies over polyclonal antibodies.

How should you approach this assignment? Use the questions provided as your guide. You are not responsible for everything in the packet but you will see some of these questions again on exam 1. Note that sometimes you must speculate- try to come up with a plausible answer. Don’t worry excessively about not getting it “right”. Some answers are not even known at this point.

This must be typed in a word document and in your own words, No Plagarism!

Assignment Parts:
Part 1: Presentation Details: Provide your name, the full name of the speaker, the title of the presentation that
you viewed, and the SSS assignment number( Science speaker series 1).

The link for the video is here :

Part 2: Course Connection (~200 words). Describe an ecological concept, principle, and/or theory that was
discussed in the scientific presentation (SSS) you viewed. The description should be detailed enough for the
instructor to know that you viewed (in it’s entirely) and understood the scientific presentation. Once you have
described the ecological concept, etc., connect it to ecology course material. The connection could be to SimUText
material , which is intrinsically connected to your Ecology Photos of plants, animals. The description and connection should include at least 3 bolded
vocabulary terms that have been discussed in class. These vocabulary terms should be interwoven into your
connection paragraph and you must demonstrate your understanding of the terms you are using (i.e. do not just
list terms, but explain the why and how behind the connection). Finally, what are the broader ecological and
societal implications outlined by the speaker in their presentation (they may not always clearly state the
importance, but you should be able to identify it based on the presentation). Note: not all SSS are strictly ecologybased presentations, but all will connect to course material.

Part 3 Personal Connection (~200 words): Explain how this scientific presentation extends your personal
knowledge and understanding of ecology. How was your perspective on a given issue, concept, idea broadened
and/or changed? In this section, you may pull from your knowledge beyond our ecology classroom. Perhaps, for
example, you view the SSS on diseases, and notice it connects to the immunology, biostatistics, and/or a GenEd
course you took. In this section, you could explain how/why your understanding of disease was broadened,
strengthened, or changed after viewing an SSS. Alternatively, perhaps you view the SSS on urban ecology, and
reflect on your upbringing and how that shaped your relationship with nature. Or you explore how this new knowledge may influence or impact your future. So again, explain the why and how of your personal connection
to SSS material. One connect on a personal level is to think about the importance that this presentation and its
content has to your life (present and/or future). How does it make you see the world differently? What kinds of
biological, ecological, and/or societal questions are you left with after this presentation? There are many different
ways to approach this Part, but the important piece is digging deeper into your personal relationship with the SSS
material presented. You can always run an idea by your instructor!

Bonus! 1-2 pts: write down one original, well-thought-out question you have for the science speaker about their
presentation. To get full credit, the question must indicate that you watched the video. You will not get credit for
asking “where did you get your degree?” and the like, which could be asked of any speaker without viewing the
videos).

help answer questions answers should be detailed

a) Explain the advantages and disadvantages of a respiratory pigment with relatively low O2 affinity in terms of its loading and unloading gas properties.

b) A fish swims from a body of cool water into a body of warm water. As its body temperature rises, its rate of O2consumption increases. The warm water, however is likely to have a lower concentration of dissolved O2 than the cool water because the solubility of O2 in water decreases as temperature increases. These two factors taken together, an increase in the fish’s rate of O2 consumption and a decrease in the dissolved O2 concentration of its environmental water, can make it difficult for the fish to obtain enough O2 to meet its needs. The two factors can act as a two-pronged trap. Actually, however, the fish may face a three-pronged trap. How is the increase in temperature likely to affect the O2 affinity of the fish’s hemoglobin, and how could the effect on hemoglobin add even further to the challenge the fish faces? Does global warming pose concerns of this sort?

c) To study the chemical properties of the blood hemoglobin of a vertebrate, it might seem convenient to remove the hemoglobin from the red blood cells so that hemoglobin is in simple aqueous solution. However, removing the hemoglobin from red blood cells often promptly alters its O2-binding characteristics. Explain why?

This assignment consists of five questions. Each of your responses should be one or more paragraphs long, depending upon the depth of the question. An answer consisting of only a few short sentences is insufficient, and will receive a poor grade. Be sure to cite any and all sources correctly so that your academic integrity is not called into question. 2-3 Pages will suffice. (At least 1000 words)

Copy the following questions, add your answers, and submit them below in one attached document.

1. Explain where proteins are synthesized and then trace different routes taken by various types of proteins from the site of initial manufacture to the ultimate destination in the cell.
2. Discuss the major functions of the cytoskeleton and describe how its various components carry out these functions.
3. How do extracellular components and connections between cells help cells coordinate cellular activities? Give specific examples for plant cells and animal cells.
4. Describe the structure of the cell membrane and explain the functions of its various components. Be sure to indicate how components contribute to the membrane’s selective permeability.
5. Discuss bulk transport, passive transport, and active transport. Describe differences in the movements of substances and the actions of the cell membrane in each case.

Question 1:

Your task is to take a virtual tour into a jar of pond water. You can click on the organisms to get an idea of what each organism is. This is the link that will give you the tour:

Virtual Pond Dip

Once you tour the pond water, choose your favorite organism and describe the following for this organism.

• Detailed cell structure of the organism (Include locomotive structures, composition of cell wall and any special organelles)
• Nutrition of the organism
• Classification
• Importance in the food chain and pond ecosystem.

Question 2:

Describe in detail the cell wall structure of Gram-positive, Gram-Negative and Mycobacterial species. Highlight the molecules that make up each cell wall and how these molecules play a role in the classification of these bacteria.

Question 3:

Case Study from Chapter 12

Matt was not in good shape and it had nothing to with the time spent at the gym. It had to do with the ball of fungus in his right lung. That fungal sphere, Aspergilloma had started as a single spore of ascomycete fungus called Aspergillus. The mold had formed the mass of fungal hyphae that was invading the airways of his lung and slowly killing him. Such bronchopulmonary Aspergillus is a rare but increasingly frequent pathogen of the immunocompromised.

Besides experiencing difficulty in breathing, fever and chest pain, Matt most hated coughing up wads of bloody mucous. His disease had invaded his blood and was now progressing to his brain. Soon it might lead to paralysis.

Matt spent 4 weeks at the hospital and thankfully a new antifungal drug, Voriconazole brought Matt back to life.

How could a microbiologist determine that the fungus infecting Matt is an Aspergillus not any other fungus?

Through research look up how antifungal drugs work and explain how the drug might have neutralized the fungal hyphae.

Your answers should be detailed and you will be graded on the quality and quantity of your answers. Please provide a minimum of 3 citations in your assignment. All scientific journals need to be cited in the APA format.
