Cellular Respiration/Fermentation Review Sheet
1. Write the chemical equation for cellular respiration. Circle the reactants and
underline the products.
C6H12O6 + O2
CO2 + H2O + ATP (ENERGY)
2. Where in the cell does cellular respiration occur?
MITOCHONDRIA
3. Label the parts of the mitochondria - outer membrane, inner membrane, cristae
(folds on the inner membrane), fluid matrix
INNER
MEMBRANE
OUTER
MEMBRANE
CRISTAE FILLED
WITH FLUID
MATRIX
4. Where do we get glucose from?
THE FOOD WE EAT
5. What gas combines with glucose in order for glucose to break down?
OXYGEN
6. What type of organisms carry out cellular respiration?
ALL LIVING THINGS
7. What does cellular respiration produce for our cells?
ENERGY
8. Where is the energy in glucose stored?
ATP MOLECULES
9. What do humans & animals do with the CO2 produced when glucose breaks down?
EXHALE AS A WASTE PRODUCT
10. What do plants do with the CO2 produced during cellular respiration?
THEY STORE IT IN THEIR CELLS & USE IT FOR PHOTOSYNTHESIS
11. What do we do with the H2O produced when glucose breaks down?
STORE IT, USE IT TO MAINTAIN CELL HEALTH, OR EXCRETE AS A WASTE PRODUCT
12. What do plants do with the H2O they produce during cellular respiration?
THEY STORE IT IN THEIR CELLS & USE IT FOR PHOTOSYNTHESIS
13. Name 5 ways we use this energy.
ANSWERS WILL VARY – ENERGY IS NEEDED TO DO EVERYTHING/SURVIVE!
14. What does glycolysis mean?
BREAKING/SPLITTING GLUCOSE
15. Where in the cell does glycolysis occur?
CYTOPLASM
16. What is glucose broken down into during glycolysis? PYRUVATE/PYRUVIC ACID
17. Does glycolysis need/require O2?
NO
18. Is glycolysis an anaerobic or aerobic process? ANAEROBIC (WITHOUT OXYGEN)
19. Where do the ATP’s that start glycolysis (stage 1) come from?
STORED ENERGY
20. What’s the function of the Krebs Cycle and Electron Transport Chain (stage 2)?
TO MAKE ATP (ENERGY)
21. What does fermentation mean?
RESPIRATION WITHOUT OXYGEN
22. Name the 2 types of fermentation.
ALCOHOLIC & LACTIC ACID
23. What organisms carry out alcohol fermentation?
24. Does alcohol fermentation require oxygen?
YEAST & BACTERIA
NO (ANAEROBIC)
25. Why does bread dough rise? DURING FERMENTATION, THE YEAST PRODUCES CO2
26. After we exercise strenuously our muscles are sore. Why?
WE EXERT/BURN ENERGY FASTER THAN WE ARE REPLACING IT AND IT CAUSES
LACTIC ACID TO BUILD UP WITHIN OUR MUSCLES. OUR MUSCLE CELLS ARE FORCED
TO PROVIDE ENERGY WITHOUT ENOUGH OXYGEN.
27. Does lactic acid fermentation require oxygen?
28. Does cellular respiration require oxygen?
NO (ANAEROBIC)
YES (AEROBIC)
29. How often does cellular respiration occur in our bodies?
CONTINUOUSLY
Complete the table. Answer the following questions in the appropriate box.
Animals
Plants
How do these
organisms
obtain the
oxygen they
need for
cellular
respiration?
BREATHE IT IN FROM THE
ATMOSPHERE
WITHIN PLANT TISSUES AS A
RESULT OF PHOTOSYNTHESIS
(SOME IS REALEASED, SOME IS
STORED WITHIN THE CELLS OF
THE PLANT)
How do these
organisms get
the glucose
they need for
cellular
respiration?
HETEROTROPHS
(CONSUME FROM PLANTS OR
OTHER ANIMALS)
AUTOTROPHS
(MAKE IT DURING
PHOTOSYNTHESIS)
How do these
organisms get
the water they
need for
cellular
respiration?
STORED IN VACUOLES
STORED IN VACUOLES
What do these
organisms do
with the water
made during
cellular
respiration?
STORE IT, USE IT FOR CELLULAR
ACTIVITY, EXCRETE IT AS A
WASTE PRODUCT
USE IT FOR PHOTOSYNTHESIS
What do these
organisms do
with the
carbon dioxide
made during
cellular
respiration?
EXHALE IT AS A WASTE
PRODUCT
USE IT FOR PHOTOSYNTHESIS
What do these
organisms do
with the ATP’s
made during
cellular
respiration?
40% USED FOR SURVIVAL AND
CELLULAR ACTIVITY
60% RELEASED AS HEAT
STORE AND USE FOR SURVIVAL
AND CELLULAR ACTIVITY
