Answer #1

ANSWER :

14. During the light dependent reactions of photosynthesis, ATP (energy currency) formed when hydrogen ions (H+) move through ATP synthase from the thylakoid space to the stroma (or matrix) of the chloroplast. Hence the corresponding statement is true.

15. During the light reactions of photosynthesis, water is oxidized to form oxygen, while CO2 get reduced during the dark reactions into the glucose (C6H12O6) via gaining hydrogen ions. Hence the corresponding statement is false.
