Anaerobic Respiration
What if there is not enough
oxygen to do aerobic respiration?


Some organisms, such as yeast and some
bacteria, do not require oxygen and can survive
on a less efficient way of getting energy
Other organisms that generally require oxygen
sometimes don’t have enough for all their cells
to do aerobic respiration so they can use a less
effiecent way of breaking down glucose which
keeps their electron carriers available for when
the cells get oxygen again.
Anaerobic Respiration



No Oxygen required.
Also called Fermentation.
2 types: alcoholic and lactic acid

Both start with glycolysis


Pyruvate and 2 ATP produced
No Krebs or electron transport chain.
Lactic Acid

Pyruvate lactic acid


Carried out by your muscles
when you’re exercising hard
and can’t get enough oxygen
fast enough (can’t do aerobic
respiration)
Causes muscle cramps and
soreness
Alcoholic

Pyruvate


ethyl alcohol
Carried out by yeast and some
bacteria.
Used in brewing beer, making
wine, and baking bread and
cakes
