High Energy Electrons in Cellular Respiration
For students, one of the hardest concepts in biochemistry to grasp is the harvesting of electrons from glucose in cellular respiration.
Demonstrate how an instructor could create an assignment unique to this core content that specifically address two concepts:
What is a high energy electron?
What is an electron carrier (NAD+)?
Provide a quick summary of the assignment and applicable resources available, as well as critical-thinking questions, discussion questions, and/or potentially good short answer questions that could accompany the assignment you develop.

Discussion
Students will write a 1500 or more words research paper in the “Chemistry or Biology
Careers” category. Science buddies has a list of over 100 science related careers that
you can choose from. https://www.sciencebuddies.org/science-engineering-careers.
Your paper must be composed of three main parts have a cover page (1st page) and a
works cited (last page) with the body of the paper in the middle, all parts in MLA
style (Google it!).
The body of your paper must be typed using double space paragraph format on the
entire paper, including the cover page, and the works cited page. (This means skip a line
between every sentence. In word, go to ""format,"" then in format scroll down to
""paragraphs"" and in there is a box called ""spacing,"" scroll down to ""double"" and it will
automatically double space for you.). HEY, DON’T TRY TO PLAY ME ☺
You must use standard-sized paper (8.5″ x 11″) with 1 inch margins on all sides and 12
point size Times New Roman font. The use of double space, font style, and font size
applies to ALL PARTS of your paper.
Cover page Example In the middle of the paper, centered (1st Page):
""Title (you choose title)""
""Full Name""
“Section Number”
""Mrs. Warren-Moteane – Chemistry""
""Due date (top of this page)""
Introduction:
At the end of your introduction include a thesis statement. A thesis statement usually
appears near the end of the introductory paragraph of a paper, and it offers a concise
summary of the main point or claim of the essay, research paper, etc. A thesis
statement is usually one sentence that appears at the end of the first paragraph, though
it may occur as more than one. The thesis statement is developed, supported, and
explained in the course of the paper by means of examples and evidence.
Body/paragraphs :(Answer all questions)
1. What type of Schools offer this major/area of study?
2. What are the admissions criteria to get into these colleges?
3. What classes are needed to obtain this career?
4. What are the costs to obtain this major?

9. What are the salaries for the job starting, middle, and max?
10. What is the projected need for this career?
11. Where is this career popular (state, country location)?
Final paragraph of paper: Would you want to do this job and would this job be
favorable from an economic point of view i.e. would this job give you the life style you
want or afford you the things you want to buy? Would this job we worth the investment
put in i.e. time and money for your education. Give reasons to explain your decision.

Project
By the end of the 1880s, the introduction of lengths of celluloid photographic film and the invention of motion picture cameras, which could photograph an indefinitely long rapid sequence of images using only one lens, allowed several minutes of action to be captured and stored on a single compact reel of film. Some early films were made to be viewed by one person at a time through a ""peep show"" device such as the Kinetoscope and the mutoscope. Others were intended for a projector, mechanically similar to the camera and sometimes actually the same machine, which was used to shine an intense light through the processed and printed film and into a projection lens so that these ""moving pictures"" could be shown tremendously enlarged on a screen for viewing by an entire audience. The first kinetoscope film shown in public exhibition was Blacksmith Scene, produced by Edison Manufacturing Company in 1893. The following year the company would begin Edison Studios, which became an early leader in the film industry with notable early shorts including The Kiss, and would go on to produce close to 1,200 films.
