Living
organisms
require
to perform cellular work.
Energy
flows into most ecosystems as
and
leaves
as
.
Electron
transfer drives the transformation of energy and occurs through
reactions
.
Molecules such as NAD
+
and FAD act as electron
in redox
reactions
.
In cellular respiration,
redox
reactions occur in a series of steps called the
transport
chain
to form
.
Cellular
respiration
comprises three metabolic stages:
,
acid cycle, and
phosphorylation.
occurs in the

from the metabolism of one
molecule

The

converted
to
CoA, which enters the
acid
cycle
.
During
phosphorylation, NADH and FADH

donate
to the
ETC
to produce even more
ATP

Review: Cellular Respiration
In
conditions, glycolysis may be
followed
by
.
Other organic molecules such as
and
can also enter cellular respiration via different
pathways
.
