Respiration Review Questions:
Study the diagram of a mitochondrion:
1. Which molecule is represented by A?
a. glucoseb. water
c. CO2d. chlorophyll
2. Which molecule is represented by B?
a. N2b. Water

4. The carbon atom in CO2 is “released” from which compound during aerobic cellular respiration?
a. waterb. glucosec. saltd. chlorophyll
Study the diagram below:
7. Which of the following conclusions is best supported by data from this graph?
A. / ATP production is independent of sugar availability.B. / The amount of cellular respiration is constant in muscle cells.
C. / ATP is only produced when sugar concentrations are above 4 g/L.
D. / The amount of cellular respiration increases as sugar concentration increases.
