An elevated level of the enzyme alkaline phosphatase (ALP) in human serum is an indication of possible liver or bone disorder. The level of serum ALP is so low that it is very difficult to measure directly. However, ALP catalyzes a number of reactions, and its relative concentration can be determined by measuring the rate of one of these reactions under controlled conditions. One such reaction is the conversion of p-nitrophenyl phosphate (PNPP) to p-nitrophenoxide ion (PNP) and phosphate ion. Control of temperature during the test is very important; the rate of the reaction increases 1.47 times if the temperature changes from 30 °C to 37 °C. What is the activation energy for the ALP–catalyzed conversion of PNPP to PNP and phosphate?

The state of Colorado requires oil and gas companies who use fracking techniques to return the land to its original condition after the oil and gas extractions. [Table 12.9](12-self-check-questions#Table_12_12) shows the total cost and total benefits (in dollars) of this policy.  Land Restored (in acres) | Total Cost | Total Benefit   ---|---|---   0 | $0 | $0   100 | $20 | $140   200 | $80 | $240   300 | $160 | $320   400 | $280 | $380   Table 12.9    A. Calculate the marginal cost and the marginal benefit at each quantity (acre) of land restored. See [Production, Costs and Industry Structure](7-introduction-to-production-costs-and-industry-structure) if you need a refresher on how to calculate marginal costs and benefits.    B. If we apply marginal analysis, what is the optimal amount of land to be restored?
