Hаve yоu reаd the testing instructiоns аnd pоlicies given above under Quiz Instructions? [answer] The exam requires that you have an external webcam placed on its stand about 3 feet away from your work area and 10 inches above your work surface so that your entire workspace to include your hands, papers, entire desk, computer, computer screen, and face is visible in Honorlock during the entire exam. Is your external webcam setup correctly? [answer1] According to the testing instructions and policies above, if my webcam view in Honorlock is comparable to one of the eight pictures above showing an unsatisfactory workspace view, I will receive a [answer3].  Does your workspace view in Honorlock mimic one of three pictures shown above that demonstrate what a satisfactory workspace should look like? [answer2] Please keep in mind that this is your is your last chance to correct your external webcam view in Honorlock, so please make any necessary adjustments now so you don't receive a zero on the exam or for the course. Also, here's the links to the two authorized formula sheets; click the links now to open electronic copies for the exam: Table of Integrals, Hyperbolic Formula Sheet. Finally, make sure you allot ten minutes of your testing time to show each page of your handwritten work to your webcam before you submit your exam in Canvas. Do not move or adjust your external webcam during this process.  Good luck on the exam!

Uplоаd yоur аnswers tо these questions.  а.) Glucose can be converted to fatty acids and triacyl glycerides via acetyl-CoA, but in animals, fatty acids cannot be converted to glucose. Briefly explain why. (2 pts.) b.) Plants have a way of producing the gluconeogenic precursor succinate. Briefly explain how succinate can function as a gluconeogenic precursor. (2 pts.) c.) In plants, two reactions form a bridge in the citric acid cycle between isocitrate and malate. In first of these reactions, isocitrate is cleaved or broken apart into succinate and the two-carbon atom compound, glyoxalate (CHOCO2-). The reaction of this compound with acetyl-CoA yields malate. Propose “arrow pushing” mechanisms for each of these two bridging steps and label the "key" reaction intermedate that facilitates each of these reactions.  (4 pts.) d.). What reaction in the citric acid cycle is parallel to the reaction that forms malate from glyoxalate and acetyl-CoA? (2 pt.) e.) Briefly explain how these two reactions allow plants to synthesize glucose from fatty acids.  (2 pts.) For your information: Many plant seeds are an excellent source of oils. It is these reactions that allow them to produce cellulose for growth before they are developed enough to produce glucose via photosynthesis.

Uplоаd yоur аnswers tо these questions. а.) Outline the reactions required to release a molecule of stored glucose from liver glycogen into the bloodstream. You may use acceptable abbreviations for the names of compounds--structures are not necessary. Include enzyme names or general type of enzymatic reaction for each step. (3 pts.) b.) Again in the liver, outline the series of reactions required to store a molecule of glucose as glycogen. You may use acceptable abbreviations for the names of compounds-–structures are not necessary. Include enzyme names or general type of enzymatic reaction for each step.  (3 pts.) c.) Briefly explain what provides the free energy required for the reactions outlined in part b.  (2 pts.)
