Cellular Respiration
When glucose is
phosphorylated
a series of metabolic pathways
which release energy from food and
generate ATP
an enzyme controlled process by
which a phosphate group is being
added eg. ADP + Pi  ATP
because ATP is continuously being
made at the same rate as it is being
used up
it is converted into Glucose-6phosphate (high energy)
Glycolysis
the first stage in respiration
Glycolysis occurs in
the cytoplasm
Hydrogen ions are
released from glucose
by
Citric Acid Cycle
dehydrogenase enzyme
Phosphorylation
Humans do not need a
vast store of ATP
the second stage of respiration
Citric Acid Cycle occurs the central matrix of the
in
mitochondria
Acetyl Co-enzyme A is
added to Oxaloacetate
to produce Citrate in the citric acid
cycle
The electron transport
chain consists of
protein molecules found attached to
the inner membrane of the
mitochondria
coenzymes NAD and
FAD
accept H+ ions and high energy
electrons
Electron Transport
Chain
consists of protein molecules found
attached to the inner membrane of
the mitochondria
is oxygen
The final electron
acceptor
Oxygen combines with
hydrogen ions and electrons to form
water
Substrates for
respiration
Starch, Glycogen, Sugar molecules,
Amino Acids and Fats
