Question

Photosynthesis occurs in two sets of reactions within the chloroplast - light reactions and dark reactions.

Light reactions occur in the grana, or stacks of membrane-bound disks (thylakoids), found in the chloroplast. What is the main purpose of photosynthetic light reactions?

to produce water using oxygen from the air

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

to directly convert the light energy into glucose molecules

to produce sugar molecules using ATP, NADPH, and CO2

Answer 1

i really cant say on this one i have no clue

Answer 2

in grana light energy converted into ATP and NADPH .
In dark reaction ATP and NADPH are used to form Sugar molecule called glucose .

Answer 3

got it???

Answer 4

so it would be B

Answer 5

yeah it is B .
