Which ties to the Calvin cycle because it gives photosynthesis a pathway of light reactions and dark reactions.

What is the link between the light reactions and the Calvin cycle during photosynthesis?

Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2

i am positive it is c. condensing but i may be wrong

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:
