Name _____________________________________Homework – Ms. Burnam / AP BIOLOGYEducation Is Freedom!Date: DATE \@ "M/d/yyyy" 4/19/2013AP Biology Review Unit: Diving into MacromoleculesTHREE WEEKS UNTIL OUR AP EXAM – Monday, May 13, 2013 at 8:00AM!Directions: Here is your first assignment to help you improve your AP Bio knowledge and score by 10pts.You will need to do some research to answer many of these questions. Use your Campbell text, review book (which may not be sufficient for ALL answers) and online resources. The questions are designed to push your thinking. While this packet only has 13 problems but should take you 30-60 minutes to complete properly. Write all answers in complete sentences. Understand (2pts each)What is the difference between a covalent bond and an ionic bond? Provide two examples of each bond type. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________What is dehydration synthesis? Provide an example of dehydration synthesis. Draw your example by drawing each molecule and showing how water is lost in the process of the reaction. Name each molecule in your drawing.________________________________________________________________________________________________________________________________________________________________________________________________________________________________Drawing:DNA always forms 5’ to 3’. What is the significance of this denotation? Why is the 5’ end called 5’? Why is the 3’ end called 3’? You may label a drawing of DNA to explain.________________________________________________________________________________________________________________________________________________________________________________________________________________________________ A molecule of DNA or RNA is a polymer of __________________________________? What are the five types of the monomer you wrote in the blank?When it comes to storage and solubility in water, what is the difference between starch and cellulose?________________________________________________________________________________________________________________________________________________________________________________________________________________________________What structural difference exists between unsaturated and saturated fats? Which is more harmful? Why?________________________________________________________________________________________________________________________________________________________________________________________________________________________________Draw an amino acid with an amine group, R group and carboxyl group (-COOH)________________________________________________________________________________________________________________________________________________________________________________________________________________________________What are three properties of water? How is each property helpful to living things?________________________________________________________________________________________________________________________________________________________________________________________________________________________________Apply (3pts each)Animals can use starch as an energy source but not cellulose. Why?________________________________________________________________________________________________________________________________________________________________________________________________________________________________A mutation that alters a single amino acid within a protein cal alterThe primary level of protein structureThe secondary level of protein structureThe tertiary level of protein structureAll of the choices are correctExplain your answer: ____________________________________________________________________________Synthesize (4pts each)How do the four major macromolecules differ from one another, how does the structure of each relate to its function?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Hydrogen bond and hydrophobic interactions each play an important role in stabilizing and organizing biological macromolecules. Consider the four major macromolecules. Describe how these affect the form and function of each type of molecule. Would a change in hydrogen bonds affect form and function? Hydrophobic interactions?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Plants make both starch and cellulose. Would you predict that the enzymes involved in starch synthesis could also be used by the plant for cellulose synthesis? Construct an argument to explain this based on the structure and function of the enzymes and the polymers synthesized.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ................
