[End-of-Chapter Problem] Many patients become resistant to HIV protease inhibitors with the passage of time owing to mutatins in the HIV gene that encodes the protease. Mutations are not found in the asparate residue that interacts with the drugs. Why not? a. The pka of that aspartate is too high b. The pka of that aspartate is too low c. Without that aspartate, the enzyme's catalytic mechanism would not work (though it isn't part of a catalytic triad) d. That aspartate is part of the catalytic triad, and if you break the catalytica triad a serine protease no longer functions as a catalyst e. The aspartate is important in protein-protein interactions

Analysts and investors often use return on equity (ROE) to compare profitability of a company with other firms in the industry. ROE is considered a very important measure, and managers strive to make the company's ROE numbers look good. If a firm takes steps that increase its expected future ROE, its stock price will Increase Based on your understanding of the uses and limitations of ROE, which of the following projects will a manager likely choose if his or her bonus is solely based on the ROE of the next project? • Project X, with 35% ROE and a large investment, generating high expected cash flows • Project Y, with 40% ROE and a small investment, generating low expected cash flows Suppose you are trying to decide whether to invest in a company that generates a high expected ROE, and you want to conduct further analysis on the company's performance. If you wanted to conduct a trend analysis, you would: Compare the firm's financial ratios with other firms in the industry for a particular year Analyze the firm's financial ratios over time You decide also to conduct a qualitative analysis based on the factors summarized by the American Association of Individual Investors (AAII). According to your understanding, a company with one key customer is considered to be risky than companies with several customers. The American Association of Individual Investors (AAIT) has identified several qualitative factors that should also be considered when evaluating a company's likely future financial performance. Consider the scenario and indicate how you would expect the described event or situation to affect the described business organization. Northern Services Inc. To date, Northern has been a one-product company. It manufactures, sells, and services only one product, AM-FM radios, and that item is in the market-saturation stage of its product life cycle. As a result, Northern's profits are declining due to increased competition from new products and competing firms. For several reasons, attempts to develop and introduce new products have not been successful.
