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 PGA.
D)ATP is phosphorylated to yield ADP.
E)Light is absorbed and funnelled to reaction-centre chlorophyll a.

Question

Quizplus · Accepted Answer

The event that occurs in the light reactions of photosynthesis is the absorption of light energy by pigments such as chlorophyll and the transfer of that energy to reaction-center chlorophyll a. This is required as a source of energy to charge the electrons that will later be used in the production of ATP and NADPH. Therefore, the option E is the best choice. Options A, B, C, and D pertain to events in the dark reactions (Calvin cycle) of photosynthesis.
