Question

Which protein complex absorbs the energy that is used to produce NADPH?

Answer 1

The answer for the question above is the photosystem I
Photosystem I is the second photosystem in the photosynthetic light reactions of algae, plants and some bacteria. It is an integral membrane protein complex that uses light energy to produce the high energy carriers ATP and NADPH.

Answer 2

The protein complex Photosystem 1 absorbs the energy that is used to produce NADPH. It uses these high-energy electrons to reduce NADP+ to NADPH.
