The oxygen consumed during cellular respiration is involved directly in which process or event?
- ✔✔accepting electrons at the end of the electron transport chain
Which of the following indicates a primary path by which electrons travel downhill energetically
during aerobic respiration? - ✔✔glucose → NADH → electron transport chain → oxygen
In addition to ATP, what are the products of glycolysis? - ✔✔NADH and pyruvate
Carbon dioxide (CO2) is released during which of the following stages of cellular respiration? -
✔✔oxidation of pyruvate to acetyl CoA and the citric acid cycle
Which of the following molecules donates electrons directly to the electron transport chain at
the highest energy level? - ✔✔NADH
What is the source of the energy used to generate the proton gradient across the inner
mitochondrial membrane? - ✔✔redox reactions in the electron transport chain
Which of the following molecules are products of the light reactions of photosynthesis that are
utilized in the Calvin cycle? - ✔✔ATP and NADPH
Where does the Calvin cycle take place? - ✔✔stroma of the chloroplast
Which of the following reactions produces the oxygen released by photosynthesis? -

, In chemiosmosis in mitochondria, protons flow from the intermembrane space into the matrix.
In what direction do protons flow during chemiosmosis in chloroplasts? - ✔✔from the
thylakoid space to into the stroma
A reduction in the amount of NADP+ available in plant cells in the light will ultimately result in
which of the following effects? - ✔✔a decrease in the rate of linear electron flow
Where are ATP synthase complexes located in a plant cell? - ✔✔thylakoid membranes and
inner mitochondrial membranes
A flask containing photosynthetic green algae and a control flask containing water with no algae
are both placed under a bank of lights, which are set to cycle between 12 hours of light and 12
hours of dark. The dissolved oxygen concentrations in both flasks are monitored. Predict what
the relative dissolved oxygen concentrations will be in the flask with algae compared to the
control flask. - ✔✔the concentration of dissolved oxygen in the flask with algae will be higher
in the light but lower in the dark
What is the primary function of the Calvin cycle? - ✔✔to produce simple sugars from carbon
dioxide
How would you predict that doubling the atmospheric CO2 concentration would affect C3
plants? - ✔✔they will experience increased rates of photosynthesis and growth
Which of the following statements best represents the relationships between the light
reactions and the Calvin cycle? - ✔✔the light reactions provide ATP and NADPH to the Calvin
cycle, and the Calvin cycle returns ADP, ℗i, and NADP+ to the light reactions
