AP Biology: Macromolecules; Questions & Answers
100% Solved
Macromolecules Correct answer-Molecules composed of thousands of atoms: the four
main classes being carbohydrates, lipids, prteins, and nucleic acids
Polymer Correct answer-Chainlike molecules, consisting of many similar or identical
building blocks linked by covalent bonds.
Monomer Correct answer-Make up polymers: connected by covalent bonds.
Dehydration Synthesis Correct 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 Correct answer-Adding water to reverse dehydration synthesis, so the polymer
recieves a hydrogen atom and a hydroxyl group
Carbohydrates Correct answer-A macromolecule made up of C, H and O, with a 2:1 ratio
between the hydrogen and oxygen.
Monosaccharides Correct answer-Simple sugars with 1 ring: Provides immediate energy,
classified by the amount of carbons
Disaccharides Correct answer-Double sugars with 2 rings

Polysaccharides Correct answer-Polymers, with many rings, joined by glucosidic linkages.
Acts as an energy storage macromolecule, building materials for cells or whole organisms
Maltose Correct answer-A disaccharide formed by joining the two glucose molecules:
found in malt sugar
Sucrose Correct answer-A disaccharide formed by joining glucose and fructose, major
form of sugars in plants: found in table sugar
Lactose Correct answer-A disaccharide formed by joining glucose and galactose. People
who lack the enzyme to digest this sugar are "intolerant"
Glucosidic Linkages Correct answer-the bond that bonds polysaccharides
Starch Correct answer-During photosynthesis: glucose is a biproduct that is stored in
plastids and chloroplasts
Cellulose Correct answer-Made up cell walls of plants, using beta rings
Glycogen Correct answer-An animal polysaccharide. Human produces excess sugar, highly
branched. Humans and vertebrates store this in the liver and muscles
