Question 11

Which statement best summarizes how the light-dependent reactions and light-independent reactions (Calvin cycle) work together during photosynthesis?

Accepted Answer

The light-dependent reactions capture energy and the light-independent reactions use that energy to make glucose

Answer

The light-dependent reactions take in glucose (food energy) and the light-independent reactions use the glucose to make ATP
