Anaerobic respiration in plants and yeast:
Glucose à
carbon dioxide + ethanol (+small amount of energy)
Anaerobic respiration in animals (muscles):
Glucose à
lactic acid (+small amount of energy)
Anaerobic respiration produces an
oxygen debt (where oxygen is need to be taken in to break down the lactic acid
that builds up in the muscles/respiring cells.
Lactic acid is what causes cramps.
It breaks down to carbon dioxide + water (by oxygen)
The oxygen debt is the reason we
breathe deeply and quickly after exercise: to break down lactic acid (because
of oxygen), increase oxygen intake which helps to “repay” the oxygen debt or to
use it to respire aerobically.
