The precise moment when light energy is transformed into chemical energy is the point at which A) light shines on chlorophyll. B) water is hydrolyzed. C) the P₆₈₀ chlorophylls are oxidized. D) chlorophyll is reduced. E) the CO₂ from air is captured in a sugar.

Question

Quizplus · Accepted Answer

The P₆₈₀ chlorophylls are a part of the photosystem I complex that is responsible for absorbing light energy and using it to transfer electrons through a series of reactions, ultimately leading to the reduction of NADP+ to NADPH. This is the point where light energy is transformed into chemical energy in the form of high-energy electrons stored in NADPH.
