AP Biology: Macromolecules Exam Questions With Correct Answers 100% Verified. Macromolecules - answerMolecules composed of thousands of atoms: the four main classes being carbohydrates, lipids, prteins, and nucleic acids Polymer - answerChainlike molecules, consisting of many similar or identical building blocks linked by covalent bonds. Monomer - answerMake up polymers: connected by covalent bonds. Dehydration Synthesis - answer(Condensation Reaction): Covalent bonds which connect monomers have distinct functions: One monomer provides a hydroxyle group and the other provides a hydrogen, creating water (as a biproduct) and a bond between the monomers. Hydrolysis - answerAdding water to reverse dehydration synthesis, so the polymer recieves a hydrogen atom and a hydroxyl group Carbohydrates - answerA macromolecule made up of C, H and O, with a 2:1 ratio between the hydrogen and oxygen. Monosaccharides - answerSimple sugars with 1 ring: Provides immediate energy, classified by the amount of carbons Disaccharides - answerDouble sugars with 2 rings Polysaccharides - answerPolymers, with many rings, joined by glucosidic linkages. Acts as an energy storage macromolecule, building materials for cells or whole organisms Maltose - answerA disaccharide formed by joining the two glucose molecules: found in malt sugar Sucrose - answerA disaccharide formed by joining glucose and fructose, major form of sugars in plants: found in table sugar Lactose - answerA disaccharide formed by joining glucose and galactose. People who lack the enzyme to digest this sugar are "intolerant" Glucosidic Linkages - answerthe bond that bonds polysaccharides
