Which of the Events Listed Below Occurs in the Light

Question

Which of the events listed below occurs in the light reactions of photosynthesis?
A)NADP is produced.
B)NADPH is reduced to NADP⁺.
C)Carbon dioxide is incorporated into 3-phosphoglycerate.
D)ATP is phosphorylated to yield ADP.
E)Light is absorbed and funnelled to reaction-centre chlorophyll a.

Accepted Answer

The event that occurs in the light reactions of photosynthesis is the absorption of light and funneling to reaction-centre chlorophyll a. This occurs in the thylakoid membrane of chloroplasts, where pigments such as chlorophyll and accessory pigments absorb light energy and transfer it to reaction-centre chlorophyll a. This event starts the process of photosynthesis and generates ATP and NADPH, which are used in the subsequent dark reactions to convert CO2 into glucose.
