Question
Which of the following is carrying energized electrons produced by the light reactions?Group of answer choicesNADP⁺NADHNAD⁺G3PNADPHchlorophyll bchlorophyll a
Solution
The molecule that carries energized electrons produced by the light reactions is NADPH.
Here's a step-by-step explanation:
-
In photosynthesis, light reactions occur in the thylakoid membranes of the chloroplasts.
-
The light energy absorbed by chlorophyll a is used to drive the transfer of electrons and hydrogen from water to an electron acceptor called NADP⁺, reducing it to NADPH.
-
NADPH is a carrier molecule, it carries the high-energy electrons produced in the light reactions to the next stage of photosynthesis, the Calvin cycle.
So, the answer to your question is NADPH.
