**I will post my peers response to the discussion as soon as someone posts. Please respond to my classmates post on a separate document.

Please be sure that your comments to peers are substantive (see the Grading Rubric below). You should have a minimum of two postings for each thread and you will need to answer any questions I might ask you.

Make good use of the information in your textbook as well any resources you find online! Don't forget to correctly cite any source you use.

Points will be deducted for incorrectly cited references, lack of references and missed deadlines!

The following rubric will be used to score your discussion postings. There are 10 pts possible on each Discussion topic:

Points	Criteria
9-10 (Excellent)	Initial posting went beyond a basic response and provided a critical examination of the issue and/or demonstrated critical thinking. Follow-up response added new insight to the discussions and promoted ongoing dialogue. No errors in grammar or spelling
6-8 (Good)	Initial response conveyed the basic information and showed good content knowledge, but needed to expand on the reasoning and logic. Follow-up response would have benefited from incorporation of critical analysis and insight. Few errors in grammar or spelling with meaning very clear
4-5 (Fair)	Discussion addressed the main points but lacks explanation or elaboration. Follow-up response provided minimal information and need significant improvement. Many errors in grammar or spelling making posting unclear.
0-3 (Poor)	Initial response was vague, irrelevant or off-topic and/or was posted late or not all. Follow-up response was missing. Posting has so many errors in grammar and spelling that topic is not answered.

Discussion Topic

Cellular Respiration and Fermentation

You have learned this unit that cellular respiration can occur with (aerobic) or without (anaerobic) the presence of oxygen.

Briefly differentiate between the two processes, including the reactants and products of both and the relative energy yield.
Under what condition might our own cells use anaerobic respiration and why?
Describe an example where humans commercially utilize anaerobic respiration; be specific about the purpose, the organisms used and the products.
