1 Project 2: The Grinch and His Gut Potential Credits: /10 Name: Project Goals:! to practice and demonstrate your understanding of the chemical structures of the major classes of biological molecules found in our diet and of the accessory organs responsible for helping to digest them Instructions:! Please read the Unit 8 Lessons in their entirety.! Please read the poem below and use the hints within to solve the riddle and save the Grinch. Marking Guide:! identification of the chemical structures on "box" 1 /1! identification of the chemical structures on "box" 2 /1! identification of the chemical structures on "box" 3 /2! identification of which accessory organ is in each "box" /3! explanation of how the accessory organ within each "box" is involved in digesting or regulating the chemical structures shown on each "box" /3 Total = /10 Page 1 of 5

2 The Grinch and His Gut The Grinch hated Christmas! The whole Christmas season! They said, "Don't ask why, no one quite knows the reason. It could be that his head wasn't screwed on quite right. It could be, perhaps, that his shoes were too tight." Then they thought that the most likely reason of all May have been that his heart was two sizes too small. But when they took a closer look and a very long pause, They discovered his heart just wasn't the cause. It was fine, it was right, it was really quite strong! Rather it was his digestive system that had it all wrong! Lipids, proteins, carbs, whatever he ate, The more he felt empty, the more he would hate! Oh he wanted to join in the joyous Who Feast, To partake in Who pudding and rare Who roast beast, But his pesky accessory organs insist that he shan't, Because to do what they must, they just simply can't But a tear for himself the Grinch will not shed, Thanks to you and your help, he is soon to be fed. A transplant you will give him, three organs a must, Before his soul shrivels and we're left with his dust, The organs, they come in black boxes sealed tight, With labels, the symbols, they must be read right, The pancreas, the gall bladder, the liver you see, Transplant in this order; one, two and three! You can't open the boxes, not early, not late, It's in the correct order or he's doomed a death fate. So identify each box, you must do this job first, Or the Grinch he will swear, that with you he is cursed. So go ahead, use your brain and all of your time, For it's about the right answer and not just a rhyme. Molecules on labels, the organs will help to digest, But beware one is trickier, even stickier than the rest, For one molecule digest, the organ just will not do, But keeping it balanced, that's the real clue, Hormones into blood it does not secrete, But responding to such, its job is so sweet. Now read this last paragraph and then turn the page, For thinking and answering is the last stage, Look at each label and think about digest, Give the box a correct answer and give it your best, Explain how you know which organ is which, Do it now and do it right, with nary a hitch!
