The two steps in photosynthesis are the light-dependent reactions and the Calvin cycle.

Which of the following is true regarding these two steps?
a
The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma.
b
The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions.
c
The light-dependent reactions use ATP from the Calvin cycle, and the Calvin cycle uses energy from absorbed sunlight.
d
During the light-dependent reactions, carbon dioxide is fixed to produce sugars that form glucose.

a. The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma.
