Section 1

Question Answer
Valence (outer) electrons of a carbon atom4
Why can carbon form chains?One carbon atom can bond to another
Large molecule in living cellsMacromolecules
Process that forms large organic moleculesPolymerization
When monomers join together they form aPolymer
Carbohydrate monomer is calledMonosaccharide

Section 2

Question Answer
Control rate of reactions, regulate cell processes, form cell structures, help fight diseaseProtein
Storage, main energy source, structureCarbohydrate
Nutrients, energy storage, cell structure, create signaling moleculesLipid
Form structures within cells, carry genetic infoNucleic acid
Lipid monomer is calledFatty acid chains and glycerol

Section 3

Question Answer
Element or compound that enters into a chemical reaction Reactant
Negatively charged subatomic particleElectron
Compound that forms hydroxide ions in solutionBase
Process that changes one set of chemicals into anotherChemical reaction
Nucleic acid monomer is calledNucleotide

Section 4

Question Answer
Bond formed when one or more electrons are transferred from one atom to anotherIonic bond
Monomer of nucleic acidNucleotide
Positively charged subatomic particleProton
Substance formed by the chemical combination of elementsCompound
Protein monomer is calledAmino acid

Section 5

Question Answer
Monomer of proteinAmino acids
Compound that forms hydrogen ions in solutionAcid
Positively or negatively charged atomIon
Carbon compound that stores and transmits genetic informationNucleic acid

Section 6

Question Answer
Atom of an element that differs in the number of neutrons compared with other atoms of the same elementIsotope
Center of an atomNucleus
Basic unit of matterAtom
Bond formed when electrons are shared between atomsCovalent bond
Macromolecule formed when monomers join togetherPolymer
How did organic compounds get their namesWere once thought to only be produced by living things.
