Cellular Respiration Review
Notes
You may use your notes on the test.
Whether or not you use them you will turn them in with your test on Wed.
Cellular resp. releases energy by…A. Breaking down food moleculesB. Breaking down ATPC. Breaking down CO2
Answer is:Food molecules are broken down
to provide your cells with energy.
Know the 3 parts of Cellular Respiration(The precursor & its 2 stages)
The 3 parts are…First comes…Glycolysis
Second…Krebs Cycle
Third…Electron Transport Chain
Krebs CycleStarts with pyruvate
Produces NAD+(p. 210)
Know: e- transport chain
Occurs where?
Mitochondria, (in the inner membrane.)
*In the Cytoplasm
What does it begin with?*Glucose
Where does Glycolysis occur?
Glycolysis produces how many ATPs? (net production)
2
Know the equation for cellular respiration.
C6H12O6 + 6O2 Energy + 6H2O + 6CO2
(Balanced)
Know that the electron carrier
in cellular respiration is:
NAD+
What is the final product of lactic acid
fermentation?
Lactic Acid
What kind of cells does Lactic Acid
Fermentation mainly occur in?
Muscle cells
During Lactic Acid Ferm.
NAD+ is recycled so that ______GLYCOLYSIS____ can continue.
Hint: This produces 2 ATPs.
What are the final products of alcoholic fermentation?
CO2
EthanolUsed to make beer, wine,
alcoholic beverages.
How many ATPs are formed
from glycolysis + cellular
respiration?
36 ATPs
In Cellular Respiration
1 Molecule of glucose yields how many ATPs?
36This is glycolysis + cellular
resp.
If no oxygen is present the
cell will go through…
FERMENTATION
*AEROBIC means:
Uses OXYGEN
*ANAEROBIC means:
Uses NO OXYGEN
Cellular Respiration uses
Oxygen
Cells that don’t use oxygen / don’t go through c.r. , are anaerobic bacteria
Can cause food poisoning
