WR #4: How are starch and simple sugars related?
Carbohydrates Model - Activity
Written Response #5: What Should I Eat? For each of the scenarios below, choose between simple sugars, starches or lipids: 1. I want to swim 50 miles 2. I want to run the 100 meter dash 3. I want to prepare to live on a deserted island with little to no food (long term energy storage)
Written Response #6: Which Organic Molecule? Iodine Benedict s No test Fatty acids Nucleotide Sugars Amino acids Control genes Brown paper bag Starch Glucose Enzymes Stored energy Quick energy Biuret s Long term energy Hormones Glycerol Carbohydrates Proteins Lipids Nucleic Acids
Nucleotides Nitrogen base Phosphate Sugar

Chemical Reactions Written Response #8: 1. Draw a synthesis reaction using glucose and starch. Label the reactant(s), product(s), glucose and starch. 2. Draw a digestion reaction using glucose and starch. Label the reactant(s), product(s), glucose and starch.
Protein Denaturation If you alter the temperature or ph, you will change the shape of a protein. If you change the shape, it will no longer work properly. The protein is now denatured.
Written Response #9: Enzyme 1. At what ph would enzyme rate reach it peak? 2. What can you predict will happen to the enzyme activity if I add a strong acid? 3. What can you predict will happen to the enzyme activity if I add a weak acid? Activity
Written Response #10: Lactose Intolerance Lactose intolerance is the inability to break down lactose (sugar in dairy) due to the lack of presence of lactase (enzyme that breaks down lactose). Write a paragraph and include pictures to describe what is happening internally for a person with lactose intolerance compared to someone who is not intolerant to lactose. *Remember the enzyme-substrate complex*
Enzyme Worksheet Complete the handout and glue/tape into your notebook. If you finish before class is over, work on your vocabulary activity (due Wednesday).
Enzyme Cut-Out Activity 1. At the top of the next page in your notebook, write Enzyme Cut Out Activity 2. Complete parts A, B and C in your notebook. 3. Complete part D on the handout first and then glue/tape it into your notebook.
Written Response #11 1. Label each of the parts a-d on the diagram to the right. 2. Answer true of false to the following statements: A. Enzymes interact with specific substrates B. Enzymes change shape after a reaction occurs C. Enzymes speed up reactions. D. One enzyme can be used for many different types of chemical reactions. 3. Write the correct effect (increase, decrease, not change). A. Raising the temperature slightly will the rate of reaction B. Boiling temperature will the rate of reaction. C. Changing the ph toward the optimal ph will the rate of reaction.
