that can combine with other
like or unlike molecules to
make a polymer
Polymer- a large molecule that
is formed by more than five
monomers
Macromolecule- a very large
organic molecule, usually a
polymer, composed of
hundreds or thousands of
atoms
Adenosine triphosphate
(ATP)- an organic molecule
that acts as the main energy
source for cell processes
Carbohydrate- an organic
compound that is made of
carbon, hydrogen, and oxygen
and that provides nutrients to
the cells of living things

Mono = one
One unit
Poly = many
Many units
Macro = large
ATP = energy currency ($)
The more ATP your cells
have, the more energy they
have to do work.
Quick energy store
(Carbo load the night before a
race)
Ex. Bread and pasta
Mono = one
Saccharide = sugar
Ex. Glucose
Di = two
Saccharide = sugar
Ex. Fructose + glucose = sucrose
Polysaccharide- one of the
carbohydrates made up of
long chains of simple sugars
Protein- an organic compound
that is made of one or more
chains of amino acids and that
is a principal component of all
cells
Amino acid- an organic
molecule that contains a
carboxyl and an amino group
and that makes up proteins
Peptide bond- the chemical
bond that forms between the
carboxyl group of one amino
acid and the amino group of
another amino acid
Polypeptide- a long chain of
several amino acids
Poly = many
Saccharide= sugar
Ex. Starch, glycogen, and
cellulose
Ex. Hair, horns, skin, muscles,
and enzymes are all made of
protein.
The monomer (smallest) unit
of a protein.
20 different types
Bond holding to AAs together
Poly = many
Peptide = amino acid bonds

Word in Context
Enzyme- a type of protein or
RNA molecule that speeds up
metabolic reactions in plant
and animal without being
permanently changed or
destroyed
Substrate- the reactant in
reactions catalyzed by
enzymes
Definition in My Own Words
Picture, Memory Aid, Phrase
Speed up chemical reactions
The substance the enzyme
works on
Active site- the site on an
enzyme that attaches to a
substrate
The place where the substrate
and enzyme bind
Lipid- a large, nonpolar
organic molecule which stores
energy and make up cell
membranes
Fatty acid- an organic acid that
is contained in lipids
Fancy word for “fat”
Store 9 cal/g of energy
Phospholipid- a lipid that
contains phosphorus and that
is a structural component in
cell membranes

consisting of a long fatty-acid
chain that is joined to a long
alcohol chain
Steroid- a type of lipid that
consists of four carbon rings to
which various functional
groups are attached
Nucleic acid- an organic
compound (DNA or RNA)
whose molecules are made up
of one or two chains of
nucleotides and carry genetic
information
Deoxyribonucleic acid (DNA)the material that contains the
information that determines
inherited characteristics
Ribonucleic acid (RNA)- a
natural polymer that is present
in all living cells and that plays
a role in protein synthesis
Nucleotide- in a nucleic acid
chain, a subunit that consists
of a sugar, a phosphate, and a
nitrogenous base
Found on cell membranes
(really important function)
Found in fats or oils
Waxy surfaces on plants
waterproof it and earwax
prevents germs from entering
the ear canal.
Ex. Naturally made hormones
like testosterone and
cholesterol
Monomer unit is a nucleotide.
