in this tiny teach I'm going to compare
cellular respiration or aerobic energy
production anaerobic energy production
and fermentation in aerobic energy
production the nutrient molecule glucose
for example will have its energy
liberated through glycolysis the Kreb's
cycle and the electron transport chain
oxygen is the final electron acceptor in
the electron transport chain in aerobic
energy production one molecule of
glucose produces 38 molecules of ATP in
prokaryotes and 36 molecules of ATP in
eukaryotes some bacteria living in
anaerobic environments produce ATP via
anaerobic energy production in anaerobic
energy production the nutrient molecules
glucose for example again liberate their
energy by going through glycolysis the
Kreb's cycle and the electron transport
chain again but something like nitrate
or sulfate or other molecules can act as
the final member of the electron
transport chain in anaerobic energy
production one molecule of glucose can
produce up to 38 molecules of ATP
fermentation uses only glycolysis to
liberate the energy stored in the
nutrient molecule one molecule of
glucose therefore produces only two
molecules of ATP and it can produce
various end products depending on the
organism that's fermenting yeast produce
ethanol humans produce lactic acid
