41. In thylakoids, protons travel through ATP synthase from the stroma to the thylakoid space. Therefore the catalytic knobs of ATP synthase would be located
a. on the side facing the thylakoid space
b. on the ATP molecules themselves
c. on the pigment molecules of PSI and PSII
d. on the stroma side of the membrane
e. built into the center of the thylkoid stack (granum)
42. Which of the following statements best represents the relationships between the light reactions and the Calvin cycle?
a. The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.
b. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the cycle provides water and electrons to the …show more content…
What do they do?
a. donate electrons
b. act as reducing agents
c. act as oxidizing agents
d. transport protons within the mitochondria and chloroplasts

58 The pH of the inner thylakoid space has been measured, as have the pH of the stroma and of the cytosol of a particular plant cell. Which, if any, relationship would you expect to find?
a. The pH within the thylakoid is less than that of the stroma.
b. The pH of the stroma is higher than that of the other two measurements.
c. The pH of the stroma is higher than that of the thylakoid space but lower than that of the cytosol.
d. The pH of the thylakoid space is higher than that anywhere else in the cell.
e. There is no consistent relationship.
