Cellular Respiration Word Game Review
Directions: On the lines below, write the word or words that best fit the description on the left. When you are finished, the boxed-in letters will spell out a secret message!
1. During glycolysis, glucose is
broken down into what
3-carbon compound?
2. During the electron transport chain,
what is pumped from the matrix across
the cristae membrane into the
inner membrane space?
3. This molecule is the primary
fuel for cellular respiration.
4. This type of respiration can only
occur in the presence of oxygen.
5. The Krebs cycle occurs in this part
of the mitochondria.
6. This molecule serves as a source of
immediate energy for cellular
processes that require energy.
7. ATP are generated when hydrogen
protons cause a rotor to spin as they
flow across the cristae membrane
through this enzyme.
8. At the end of the electron transport chain,
low-energy hydrogen electrons and
hydrogen protons are combined with
oxygen to form this end product.

9. This is the nitrogen base that is found
in molecules of ADP and ATP.
10. The energy transformation that converts
the energy held in molecules of glucose to
molecules of ATP is called?
11. This molecule serves as the final electron
acceptor in the electron transport chain.
12. In the absence of oxygen, muscle cells may
convert pyruvic acid into what compound?
13. This stage of cellular respiration produces
hydrogen atoms, ATP, and carbon dioxide.
14. This type of fermentation produces carbon
dioxide which causes bread dough to rise.
15. The addition or removal of this molecule
determines whether energy is stored
or released.
16. In this stage of respiration, glucose is
converted to pyruvic acid.
17. Acetate is joined with oxaloacetic acid
to form what 6-carbon compound?
18. A large number of high-energy hydrogen
electrons are delivered to the electron
transport chain in this form.
19. The energy generated from this process
is used to pump hydrogen protons
across a membrane, generating a high
concentration proton gradient.

20. This folding and looping membrane
increases the surface area for cellular
respiration.
21. This is the cellular organelle where
aerobic respiration takes place.
22. During the oxidation, or break down, of
pyruvic acid, this compound is given
off as a waste product.
23. This type of respiration occurs in the
absence of oxygen.
24. Anaerobic respiration takes place in this
part of the cell.
25. What is the total number of ATP that can
be generated from one molecule of ATP?
26. Glycolysis does not require oxygen
and is said to be?
27. This is the type of sugar that is found
in an ADP or ATP molecule.
28. During the bridge reactions, molecules
of pyruvate are oxidized into molecules
of this 2-carbon compound.
