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 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 high-energy electrons produced from the light reactions to be used in the Calvin cycle (the second stage of photosynthesis).
So, the answer is NADPH.
