The process by which
carbohydrate molecules are
broken down to release
ATP (energy)
C6H12O6 + O2
CO2 +
H20 + ATP (Energy)
Monosaccharides are the
building blocks; sugar:
major source of energy for
the body
A substance composed of
atoms of two or more
elements linked by
chemical bonds
Attraction between
molecules of the same type;
Ex. surface tension, which
causes liquids to form
spherical droplets, is caused
by cohesion.

A protein that acts as a
catalyst and speeds up
biochemical reactions

Inorganic compound that
the body needs in small
amounts, one not made
from living things and does
not contain carbon
Stores energy; includes
fats, oils, waxes; nonpolar not soluble in water
Subunit of a carbohydrate,
ex=glucose
Group of atoms that form
the smallest unit of a
substance that can retain its
chemical properties
A subunit of nucleic acids
(DNA and RNA); consists

other; hydrophilic
Process by which
autotrophs take in sunlight,
H2O, and CO2 to make
glucose (C6H12O6) and

Organic molecule that the
body needs to regulate
body processes
The substance in which a
solute is dissolved to form a
solution; water is the
universal solvent
Energy storage molecule;
created during cellular
respiration
H2O; polar molecule that
expands upon freezing
making it less dense as a
solid than as a liquid (so ice
floats)
A molecule that contains
chains of carbon;
examples:
carbohydrates, lipids,
proteins, vitamins
A molecule that does not
contain chains of carbon;
ex=water and minerals
