Chemical process,
combining & splitting of molecules
Assembly of complex molecules from
simple molecules is a process
Breakdown of large molecules into
smaller molecules
Breakdown of carbohydrates manufactured
during photosynthesis to release ATP
Breakdown of glucose, requiring oxygen
Takes place in the Mitochondria
 Chemical
energy is released when the
molecular bonds of the sugar molecules
are broken.
 ATP
drives a variety of growth and
development of the plant
 By
product reaction are CO2 and Water
 Less
efficient form of respiration
 Does
 Used
not require oxygen
in soil and water where oxygen is in
short supply
 Some
bacteria and fungi adapted to
anaerobic respiration covert energy by
fermentation
 Produces ethyl alcohol and lactic acid
 Human
recognized the value of
fermentation in the making of silage,
beer, and wine.
 Plant
growth takes place primarily at
night when photosynthesis is shut down.
 Fueled by aerobic respiration.

Glycolysis
Acetyl CoA
Citric Acid cycle (Kreb’s Cycle)
Electron transport chain
 Glycolysis
 Acetyl
Coenzyme A
 Citric Acid Cycle
-
through the first 3 steps, hydrogen atoms
were transferred to hydrogen acceptors
NAD and FAD, forming NADH and FADH2
 Aerobic
respiration, these reduced
compounds enter the electron transport
system
 Series
of chemical reactions by which
electrons are passed from one acceptor
molecule to another.
 Oxygen
 During
is the final hydrogen acceptor.
this pathway, ATP is synthesized
by the process of chemiosmosis.
The process in which hydrogen atoms
cross the thylakoid membrane and travel
down a protein gradient, producing ATP,
This 4th stage see the production of 32 ATP
molecules. What is also made and
released (Transpiration)
