Is the bolded statement TRUE or FALSE? Enzymes: 16. lower activation energy. 17. drive all reactions to completion, converting all reactant to product (meaning that no reactant is left at the end of the reaction). 18. can catalyze a reaction in either direction. 19. are only proteins. 20. are more complementary to the reaction’s transition state relative to the reaction’s substrate.

Suppose you entered the short position of one Orange Juice futures contract on 11/27/17. The futures price was $1.04/1b. On 12/03/17, the orange Juice futures price is $0.95/lb. The contract size is 15,000 lbs. By how much should your margin account change?

Is the bolded statement TRUE or FALSE? In chapter 7 we discussed major concepts related to the kinetics of an enzymatically catalyzed reaction.  Given this classify the following as true or false. 31. Saturating conditions result in [ES] approximately equal to [ET].  32. The kcat is the largest rate constant of any of the steps employed by the enzyme. 33. Loss of an ionic bond, due to mutation of the enzyme, between the enzyme active site and the substrate will lead to a depression (making it smaller) in the Km. 34. An enzyme with a larger kcat will always be a more “efficient” enzyme, in all conditions, than the one with the small kcat. 35. If all of an enzyme is in the ES form, the enzyme will obtain its Vmax.

In a futures contract:
