Glycolysis
needs
an
input
of
ATP
to
ouptut
a
total
of
ATP
,
meaning
there
is
only
a
net
gain
of
ATP
.
Glycolysis
is
an
process
that
takes
place
in
the
of
the
cell
.
Glyclysis
begins
with
glucose
molecule
that
separates
into
pyruvate
molecules
.
The
electrons
that
are
released
by
breaking
the
bonds
are
later
carried
by
NAD
+
which
are
reduced
to
NADH
.

The

The

For

This

that
when

First
After
the
Citric
Acid

Kreb's
Cycle
,
all
Carbons
from
the
original

molecule
are
used
up

released

or
recycled
into
other
products
.
However
,
the

released
from
each
time
a

was
broken
has
been

by

Finally

if

then
