E. chlorophyll
_C___6. Process requires oxygen F. sunlight
__H__ 7. The ability to do work G. Glycolysis
__I__8. Energy storing molecule H. Energy
__G__9. The anaerobic process of splitting glucose I. ATP
and forming two molecules of pyruvic acid
__F__ 10. This starts the process of photosynthesis J. Kreb’s cycle
_B___ 11. This process does not require sunlight. K. Glucose
__E__ 12. The pigment that traps sunlight L. Autotrophs
Directions: Answer each of the following questions in a clear and concise manner. 1. Compare
lactic acid fermentation and alcoholic fermentation by describing what pyruvic acid is changed in
to. Be sure to include what type of organism each one takes place in.
What is pyruvic acid changed into?
Alcoholic Fermentation
Lactic Acid Fermentation
Organism:
ETHYL ALCOHOL
YEAST & BACTERIA
LACTIC ACID
ANIMALS/HUMANS
2. Name the three processes of aerobic cellular respiration. How many ATP’s does each process
produce, and what is the total ATP produced from one glucose?
1
3 Processes of Cellular
Respiration:
# ATP produced:
GLYCOLYSIS
2
KREBS CYCLE
2
ELECTRON TRANSPORT
CHAIN
28-34
Total ATP =__30-38ATP________
3. Name the two stages of photosynthesis and list the starting molecule(s) and ending molecule(s) of
each.
Stages
Starting Molecule(s)
Product(s)
LIGHT DEPENDENT REACTION
LIGHT & H2O
LIGHT SPLITS H2O
KEEPING THE
HYRDOGENS
O2 IS RELEASED & THE
HYDROGENS ARE TAKEN TO
THE NEXT STEP
LIGHT INDEPENDENT REACTION
HYDROGENS + CO2
C6H12O6
4. What is the general chemical equation of photosynthesisa? WATER + CARBON DIOXIDE + LIGHT (
SUGAR + OXYGEN
H2O + CO2 ( C6H12O6 + O2
5. When and why does our body use lactic acid fermentation? LACTIC ACIDS FERMENTATION
OCCURS DURING STRENUOUS EXERCISE WHEN NOT ENOUGH OXYGEN IS AVAILABLE
FOR YOUR MUSCLE CELLS TO USE TO CREATE ATP
6. Explain how the equations for photosynthesis and cellular respiration compare. THEY ARE
BASICALLY THE SAME FORMULA BUT MIRROR IMAGES OF EACH OTHER. WHAT GOES
INTO ONE PROCESS IS WHAT COMES OUT OF THE OTHER. WATER & CARBON DIOXIDE GO
INTO PHOTOSYNTHESIS AND WATER AND CARBON DIOXIDE COME OUT OF CELLULAR
RESPIRATION.
