Question

question 3
which of the following events occurs in the light reactions of photosynthesis?
nadp+is produced.
atp is consumed to yield adp.
carbon dioxide is fixed in organic molecules.
light is absorbed and transferred to reaction - center chlorophyll.

Explanation:

• In the light reactions of photosynthesis, light is absorbed by pigments (like chlorophyll) in the thylakoid membranes. This absorbed light energy is transferred to reaction - center chlorophyll.
• NADP+ is reduced to NADPH (not produced) in the light reactions.
• ATP is produced (not consumed) from ADP and inorganic phosphate in the light reactions.
• Carbon dioxide fixation in organic molecules occurs in the Calvin cycle (dark reactions), not in the light reactions.

Answer:

Light is absorbed and transferred to reaction - center chlorophyll.
