1. J. Wellington Wimpy (from unit 2, learning activity 2)
Compare 1 meal of Wimpy’s before his transformation (burger meal) to 1 meal of his after his transformation (sub meal). For each meal (before and after), list the ingredients that were likely in his meal. Then compare the macromolecules available in each meal.
Explain how these macromolecules break down in the body for energy. Include diagrams in your description. What are the major differences between the two meals? Is the turkey sub a healthier meal when looking at the macromolecules available?
Provide some tips for Wimpy to make his meals even healthier.
2. Lactose intolerance (from unit 2, learning activity 4)
Explain to Carol what is happening in her body – what does it mean to be lactose intolerant? Explain this using biology terms and concepts learned in this unit. Why does her doctor recommend that she eats yogurt?
3. Hydration and dehydration (from unit 2, learning activity 5)
Who was correct? Ellie’s father or mother? Explain the process of getting wrinkly skin and how you know they were correct. Is what happens to skin in an ocean vs. a freshwater lake different or the same? Explain this using concepts and terms learned in this unit.
you will now put everything that you have learned in the three cased studies together to present the cases as a report.
Case Study #1: J. Wellington Wimpy
Explain using words and diagrams the structure of carbohydrates
Demonstrate understanding of monomers and polymers in carbohydrates
Explain using words and diagrams the structure of proteins
Demonstrate understanding of monomers and polymers in protein
Compare primary, secondary, tertiary and quaternary structures of protein
Explain using words and diagrams the structure of fats
Compare and identify condensation (dehydration) and hydrolysis reactions
Describe the functions of carbohydrates, proteins and fats in cells and organisms
Identify some functional groups found in carbohydrates, proteins and fats
Case Study #2: Lactose Intolerance
Explain how enzymes work to speed up reactions
Explain the induced fit model of how enzymes work
Describe how enzymes are regulated (activated and inhibited)
Case Study #3: Hydration and Dehydration
Explain how osmosis works including the concept of concentration gradient
Compare passive and active transport
Describe the fluid-mosaic model of the cell membrane and how it results in a semi-permeable membrane (and what that means)
I can also provide the links for each Case Study upon request
