are
organic
compounds
produced
by
cells
and
living
organisms
.
The
four
major
types
are
carbohydrates
,
lipids
,
nucleic
acids
,
and
proteins
.
Among
biomolecules
,
nucleic
acids
,
namely
____________________
and
____________________
,
have
the
unique
function
of
storing
an
organism's
genetic
code
?
the
sequence
of
nucleotides
that
determines
the
amino
acid
sequence
of
proteins
,
which
are
of
critical
importance
to
life
on
Earth
.
There
are
____________________
different
amino
acids
that
can
occur
within
a
____________________
;
the
order
in
which
they
occur
plays
a
fundamental
role
in
determining
protein
structure
and
function
.
Proteins
themselves
are
major
structural
elements
of
cells
.
They
also
serve
as
____________________
,
moving
nutrients
and
other
molecules
in
and
out
of
cells
,
and
as
____________________
and
catalysts
for
the
vast
majority
of
chemical
reactions
that
take
place
in
living
organisms
.
Proteins
also
form
____________________
and
hormones
.
Likewise
,
carbohydrates
,
which
are
made
up
primarily
of
molecules
containing
atoms
of
carbon
,
hydrogen
,
and
oxygen
,
are
essential
____________________
sources
and
structural
components
of
all
life
,
and
they
are
among
the
most
____________________
biomolecules
on
Earth
.
They
are
built
from
four
types
of
sugar
units
?
monosaccharides
like
____________________
disaccharides
,
oligosaccharides
,
and
polysaccharides
like
cellulose
and
____________________
.
Lipids
,
another
key
biomolecule
of
living
organisms
,
fulfill
a
variety
of
roles
,
including
serving
as
a
source
of
____________________
energy
and
acting
as
chemical
messengers
.
They
also
form
____________________
,
which
separate
cells
from
their
environments
and
compartmentalize
the
cell
interior
,
giving
rise
to
organelles
.
