1. Our blood contains cells and many different types of compounds that are dissolved in water. Salts such as NaCl and CaCl? are electrolytes which dissolve and ionize in water. These electrolytes have vital functions in the body such as conducting electrical impulses, helping to maintain water balance, and participating in various chemical reactions. Why would a salt such as NaCl disassociate into ions in water but not in gasoline? Explain your answer in terms of the polarity of water vs. gasoline. 2. If you were to eat a protein bar, which chemical reactions introduced in this class must occur for the individual amino acids in the protein bar to be converted into polypeptides (a large chain of amino acids) in a muscle cell? The journey begins with chewing the protein bar and ends with the polypeptide in the muscle fiber. 3. In relation to protein structure, why is maintaining the body's internal environment so important? In your answer, be sure to relate a protein's structure to its function and what changes in variables such as temperature and pH does to a protein's structure (be sure to use scientific terminology).
