Question
Chapter 19, Problem 2P
Interpretation Introduction
Interpretation:
The component, to which the photo system donates electron.
Concept introduction:
Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is a photosystem of the photosynthetic light reactions. It is an integral membrane protein complex which uses light energy to produce high energy carrier molecules ATP and NADPH.
