A ________ is the amount of energy needed to raise the temperature of 1 gram of water 1 degree C.

3. Cellular Respiration Overview
Chem equation:

4. Occurs in
Cytoplasm of
Cells.
You must put
A little energy in!
To get a little
Energy out!!
OXYGEN IS NOT NECESSARY FOR THIS TO HAPPEN

5. Fermentation When oxygen is not present, glycolysis
is followed by FERMENTATION.
During __________________, cells convert
___________ back to NAD+
Does not require _____________, thus it
is called anaerobic.
Two types: ___________________ and
________________________.

6. Lactic Acid Fermentation

8. Aerobic Respiration

9. Pyruvic acid is
Broken down into
CO2 in a series
Of energy extracting
reactions
NADH and FADH2 (electron carriers) will be shuttled to ETC

10. Takes place on mitochondrial membrane (inner membrane)
ETC uses high energy electrons from Krebs Cycle to
convert ADP into ATP
