has mass and occupies space.
$400
What is an atom?
The smallest particle of
matter.
$600
What are compounds and an element?
CO2 and CO are both
classified as this but C by

explain two of the most
important energy
transformations that occur in
biological systems.
$400
What is metabolism?
These are all of the chemical
reactions that take place in an
organism.
$600
What is the reactants are 4 Fe and 3 O2 and
the product is 2 Fe2O3?

What is the activation energy?
This is the little (or big) push
of energy needed to get a
chemical reaction going.
$1000
What is an enzyme?
A type of protein or RNA
molecule found in a living
thing that speeds up
metabolic reactions without
being used up or destroyed.
$200
What is hydrogen bonding?
This is the type of bonding that water
molecules have due to their bond
polarity. It allows water to be cohesive,
be adhesive, have a high heat capacity,
and dissolve many other substances.
$400
What is a solute?
The substance that gets
dissolved in a solution.
$600
What is water?
This substance is considered the
universal solvent because most
things (polar substances) will
dissolve in it.
$800
What is cohesion and surface tension?
These properties of water
allows water to travel from
root to leaves in a plant and
some insects to walk on
water.
$1000
What is less?
Hydrogen bonding allows the
density of solid ice to be
________ than that of its
liquid form.
$200
What are bases?
The term alkalinity refers to
these.
$400
What is pH?
It literally means “potential
hydrogen.”
$600
What is an acid?
The properties include: gives off H+ in
solution, tastes sour, can be corrosive to
metals, and turn blue litmus red.
$800
What is gives off OH- ions in solution, taste bitter,
and turns red litmus blue?
These are three properties of a
basic substance.
$1000
What are buffers?
Our bodies have these specific
types of chemicals that maintain
homeostasis in terms of pH by
neutralizing acids and bases.
$200
What are organic compounds?
Compounds that are primarily
made of carbon.
$400
What is a monomer?
A simple molecule that can
combine with other
molecules to build bigger
molecules.
$600
What are polymers?
The GAK and slime that we
made last year are examples
of these and gummy bears
too.
$800
What are macromolecules?
A very large organic compound
composed of hundreds or thousands
of atoms. They include
carbohydrates, proteins, lipids, and
nucleic acids.
$1000
What is ATP?
Energy currency $$$$
$200
What is a monosaccharide?
A type of simple sugar (carb)
that contains carbon, hydrogen,
and oxygen in a 1:2:1 ratio. An
example is glucose.
$400
What is an amino acid?
This monomer unit of a protein that is
composed of carbon, hydrogen, oxygen,
and nitrogen. They are the building
blocks of proteins.
$600
What is a polysaccharide?
A type of complex sugar (carb)
that is composed of three or
more monosaccharides. An
example is glycogen.
$800
What are lipids?
Examples of this type of
macromolecule include
triglycerides, phospholipids, waxes,
and steroids.
$1000
