13. – 16. Write the balanced equation for cellular respiration (4 pts.)
C6H12O6 + 6 O2  energy (ATP) + 6 H2O + 6 CO2
17. – 19. Cellular respiration is often described as the opposite of photosynthesis. Do
you agree or disagree? Support your answer. (3 pts.)
agree…if you reverse the arrow in the equation
above, you pretty much have photosynthesis
(although technically photosynthesis does not
make glucose (so you might disagree), but cell
respiration definitely starts with glucose.)
20. – 22. The Krebs cycle and Electron Transport Chain can only occur in the
presence of oxygen. Describe what happens if there is not enough oxygen for
the cell. Include the amount of ATP created, waste products and any other
benefits. (3 pts.)
fermentation … lactic acid or alcohol is made
No ATP is created, but NAD+ is recycled so
glycolysis can happen again and 2 ATP made by
glycolysis
