Which question can be answered about the light-dependent reactions?

a
Where is CO2 used?
b
Where is glucose formed?
c
Where is water broken down?
d
Where is oxygen used?

Answer 1

The question that can be answered about the light-dependent reactions is:

c. Where is water broken down?

In the light-dependent reactions of photosynthesis, water (H2O) is split (photolysis) to provide electrons and protons, and oxygen (O2) is released as a byproduct.
