For this Case assignment, you will look more closely at important reactions that drive human physiology and the mechanisms by which these reactions operate.

First complete the reading in Pain-Free Biochemistry:

Chemistry: Equilibrium

Topic:  Catabolism degradation vs energy metabolism

Now use this website, All About Chemical Equilibrium at http://www.chem1.com/acad/webtext/chemeq/index.html to complete this Case assignment. 

Follow these steps to complete your Case assignment for Module 4:

1. Begin by reading the Home page, then proceed through the Introduction and Le Chatelier's Principle.
2. In The section on Le Chatelier's Principle you will find examples of how equilibrium applies to reactions in the human body.  Choose one example of an equilibrium reaction commonly found in human physiology.  Explain the significance of this reaction in the body.
3. Using the website and Appendix 4 of Pain-Free Biochemistry (Equilibrium Constant), provide the equation necessary to calculate Keq for the reaction you chose.

Assignment Expectations

Answer each question using complete sentences that relate back to the question.  Be sure to include a references section at the end of your assignment that lists the sources that you were required to read and view, and any additional resources you used to research your answers.
