Organic Compounds Exam with Correct
Answers Rated A+
Compound - ANSWER: A substance made up of atoms of two or more different
elements joined by chemical bonds.
Organic compounds - ANSWER: Compounds that contain bonds between carbon
atoms. The four major groups of organic compounds are carbohydrates, proteins, lipids,
and nucleic acids.
Inorganic compounds - ANSWER: Compounds that do not contain carbon. Examples
are water and NaCl (salt).
Lipids - ANSWER: Energy-rich organic compounds, such as fats, oils, and waxes, that
are made of carbon, hydrogen, and oxygen.
Carbohydrates - ANSWER: Class of organic compounds containing only carbon,
hydrogen, and oxygen. Examples are glucose (sugar), starch, and cellulose (fiber).
Proteins - ANSWER: Organic compounds whose building blocks are amino acids.
Nucleic acids - ANSWER: Organic compounds that include DNA and RNA. These are
information-containing molecules that give cells their instructions.
Element - ANSWER: A pure substance that cannot be broken down into a simpler
substance.
Functions of carbohydrates - ANSWER: The body's main source of quick energy;
provide structure to the cell, make up cell walls of plants.
Functions of lipids - ANSWER: Energy storage, part of cell membranes in all organisms,
insulation, protects organs.
