Question

Photosynthesis occurs in two sets of reactions within the chloroplast: light-dependent reactions

and light-independent (dark) reactions.
Light-dependent reactions occur inside grana, which are stacks of membrane-bound disks
found within chloroplasts. What is the main purpose of the light-dependent reactions?
A.
to produce sugar molecules using ATP, NADPH, and CO2
B. to convert light energy into the chemical energy of ATP and NADPH
C. to produce water using oxygen from the air
D. to convert light energy directly into glucose molecules

Answer 1

to convert light energy into the chemical energy of ATP and NADPH

Step-by-step explanation:

Answer 2

B. They use light to convert ADP + P into ATP and NADP+ to NADPH
