The stepwise formation constants for complexes of NH2CH2CH2NH2 (en) with [Cu(OH2)6]2+ (aq) are log Kf1 = 10.72 and log Kf2 = 9.31. The stepwise formation constants for complexes of NH3 with [Cu(OH2)6]2+ (aq) are log Kf1 = 4.15, log Kf2 = 3.50, log Kf3 = 2.89, log Kf4 = 2.13, and log Kf5 = -0.52. Compare the values for both substitution reactions and suggest why they are different.

Alicyclobacillus acidoterrestris is a strictly aerobic, gram-positive bacillus that produces endospores. It can survive in acidic environments down to pH 2.5 and grows at temperatures between 26°C and 55°C. The significance of this bacterium lies in its ability to contaminate juice products and survive the pasteurization process used to remove bacteria due to the heartiness of its endospores. This bacterium is found growing in soils, fruit juices, and orchards. It can easily grow in apple, orange, mango, tomato, pineapple, grapefruit, and pear juices. How would you classify its metabolism?
