Class Outlines Bring these to each class blank printed or on a tablet you can write on We will complete them IN class together You should also take notes on here for studying Life s 5 Themes Macromolecules Structure Function I REVIEW Life s common themes 1 Transformations of Energy and Matter 2 Structure and Function 3 Interactions within and between Systems 4 Flow of Information 5 Theory of Evolution Match each theme above to a statement below 1 A Red pandas share characteristics with giant pandas and raccoons but new evidence suggests they should be classified as their own family 2 B Millions of microbes live within your gut secreting a variety of proteins that may have multiple effects on your brain physiology 3 C As glucose breaks down into smaller molecules within your cells some amount of heat is lost to the environment 4 D At the end of chromosome 4 is a gene called huntingtin that when mutated causes a mutant protein to be made that has lethal effects on neurons 5 E The bladder is able to hold large amounts of urine because it is an expandable sac II Macromolecules You re running between classes so you grab a snack of an apple and low fat milk Let s look at some nutrition facts for an apple Calories 52 Water 86 Protein 0 3 grams Carbs 13 8 grams Sugar 10 4 grams Fiber 2 4 grams Fat 0 2 grams A small amount of fat is present would you expect this to be saturated or unsaturated and why You would expect it to be unsaturated Function energy storage fats more efficient way of storing energy plants generally have low fat content Carbohydrates easiest way but bulky plants use Class Outlines Bring these to each class blank printed or on a tablet you can write on We will complete them IN class together You should also take notes on here for studying Which of the four macromolecule groups does fiber fall under What are the three other macromolecule groups Fats glycerol fatty acid saturated unsaturated carbs glucose starch fiber protein amino acids nucleic acids nucleotides DNA One macromolecule group is not represented Which is missing Phospholipids What process is being shown here Hydrolysis water addition Dehydration water removal Someone who cannot digest milk and is lactose intolerant is missing the ability to do what Produce the enzyme lactase LCT gene Mammals can digest starch and glycogen but not cellulose See if you can think of a reason why Mammals don t make the enzyme that breaks down cellulose specifically All three polysaccharides have different structures and the enzyme that break them down are specific Fats and digestion a challenge for hydrophobic molecules to be transported in water based body fluids Can you design a way to transport fat molecules using phospholipids Consider what you know about the chemical properties of phospholipids Use these symbols Triglyceride fat Phospholipid Draw how triglycerides can be transported in watery fluid using phospholipids as transport molecules Class Outlines Bring these to each class blank printed or on a tablet you can write on We will complete them IN class together You should also take notes on here for studying Once in your body the monomers of your food are useful in a variety of ways III Protein Structure Amino acid Amino acid dipeptide dehydration synthesis forms the covalent bond How many unique dipeptides can be made e g Arg Leu or Ala Pro etc 400 Unique tripeptides 8 000 How big is a protein Anywhere from a few amino acids to several thousand What is the primary structure of a protein You have been hired as an illustrator for a new introductory biology textbook The authors want you to draw a picture to demonstrate how two amino acids far apart in primary structure in lactase can interact in their tertiary structure ignore secondary structure What does your rough sketch look like Draw a second stretch demonstrating what a mutation in one amino acid might do to your tertiary structure of your protein Would it affect function Class Outlines Bring these to each class blank printed or on a tablet you can write on We will complete them IN class together You should also take notes on here for studying What holds a protein s structure together What can disrupt this structure Cooking Egg video what did you learn https www youtube com watch v PxAP86zIJdc 3 min https www sumanasinc com webcontent animations content proteinstructure html 1 5 min
