Reactions that are referred to as exergonic have a negative delta G and will occur spontaneously. B. Reactions that are endergonic are usually seen in association with anabolic processes. Shmet bidons C. Reactions that are endergonic can occur by utilization of the energy released during the breakdown of an ATP molecule to an ADP molecule. boy a'adoo slova blas pidis ( D. Reactions that occur spontaneously are said to be exergonic, run uphill, have a -delta G, and require the addition of energy for the reaction to be completed. E. Reactions that are endergonic have products with more potential energy than the reactants, and result in some increase in the entropy of the universe. bas qzen neswisd rblive of sids A 81. The bacterium E. coli is known to be able to produce the amino acid isoleucine in a feedback controlled biosynthetic pathway. Which of the following statements should be true concerning this ability. bubong bre soubory of elds no exiliu at sids.0 10 wob 91d of sids.3 noftsly origaorig A.The feedback inhibition should involve the last enzyme (E4) in the biosynthetic pathway that results in the final step in the production of the isoleucine molecule. Onisono fatica a comatele pmwolldi, ert to rbiriw______.ar B. You would expect that if you manipulated the nutrient environment of the bacterium by adding more isoleucine that this biosynthetic pathway would be activated (turned on, speed up). ne dermed sili ni Hq art A amino acid isoleucine. C. The key molecule that should function as the inhibitor for the first enzyme (E₁) in this pathway should be the i gospa ensidimsmenni erT O D. You would expect that the enzymes responsible for this process (isoleucine production) are all inhibited by a molecule that binds in a competitive irreversible manner. (ABM) 10/06 E₁ E₂ E3 A--------------> B> C------------ D E4 TERBA -> isoleucine E. If an assay (chemical measure) of the levels of isoleucine production in E. coli is carried out during its normal entadong 20 minute life cycle then the activity of the pathway should not vary at all over time
