Module 2: Life’s Origin Guided NotesLesson 2.00 Life’s Origin ChecklistThis lesson shows the checklist for your module and reminds you to take the pretest.Thepretest will assess what you know already and could possibly even excuse you from some of yourwork.Make sure that when you complete the pretest, you are using your own words and yourown knowledge.Lesson 2.01 The Chemistry of Life4 main types of organic macromolecules1. carbohydrates2.lipids3.proteins4.nucleic acidsWhat do all of these macromolecules have in common?_these molecules all contain carbonatoms __CarbohydratesDefine Polymer-_sare large molecules composed of many identical or similar subunits calledmonomers.___Monosaccharides- made up of__ the smallest type of ___carbohydrate molecule2 examples-_ glucose and fructose____Monosaccarides are very important in providing_energy sources ____for the cell.All monosaccharides have the same basic formula, which is_C6H12O6____.The differences inthe behaviors of the atoms and bonds give each of the molecules a unique shape.those molecules has to do with the__function and react within a cell___of the molecule.Disaccharides- (please define) -_are carbohydrate molecules made up of two monosaccharidemolecules bonded together____2 examples- sucrose and lactosePolysaccharides- (please define) - are carbohydrate polymers made up of hundreds to thousandsof monosaccharide units bonded together.What accounts for the differences in the properties of the various polysaccharides?_how theglucose molecules are arranged____What is the monomer (single unit) that makes up the polysaccharides?_ glutose ____In 10 words or less, write what makes each type of polysaccharide important (think: function):Starch-___formed by plants to store large amounts of glutose, photosynthesis__Cellulose-__it serves as dietary fiber that regulates digestion.___Glycogen-__animals and fungi use to storeglutose molecules fromfood___Chitin-__amino groups bonded to the glutose.___LipidsNot mixing with water makes something____ Not mixing well with water is sometimes calledhydrophobic_
Three main categories of lipids are:1.Fats- Made up of 1 glycerol and__ three fatty acids, ___What is another name for fats?_ triglycerides____Why are fats important?___serve as stored energy for the organism. Fat deposits underthe skin can also provide insulation for an animal__
