RESPIRATION
}  Food
gives you
energy
once the food is
broken up into its
molecules and those
molecules are broken
apart in your cells!
-
}  During
cellular respiration, cells break
down the sugars that were in the food,
and RELEASE the energy they
contained
–  There is energy stored
in sugar molecules in the bonds between the
different atoms
–  When the bonds are broken, energy is
released
} 
The respiration equation:
C6H12O6 + O2
SUGAR
OXYGEN
ENERGY + CO2 + H20
CARBON DIOXIDE
WATER

Where does respiration take place in the cell???
In the MITOCHONDRIA!!!!
The powerhouse of the cell!

} 
We get the oxygen (O2) from the air we breath
– it is the waste product of photosynthesis
The waste product carbon dioxide (CO2) is
eliminated from our bodies as we exhale
Plants use our the waste from cellular
respiration in photosynthesis
Anyone
feeling
this
way???
} 
Fermentation – is the process of releasing energy
from sugars with out using oxygen
–  Some organisms can do this – ex. yeast
–  This is important to brewers (beer) and bakers (bread)
