ferredoxin
Quick Summary
Ferredoxins are a group of iron- and sulfur-containing proteins that act as electron carriers. They are found in photosynthetic and nitrogen-fixing organisms, as well as some anaerobic bacteria.1
In the light reactions of photosynthesis, ferredoxin plays a role in the electron transport chain. After electrons are excited by light energy and passed through various carriers, they reach ferredoxin. Ferredoxin then transfers these electrons to NADP+, helping to form NADPH, which is used in the subsequent steps of photosynthesis to create sugars.2

…which the electrons flow to ferredoxin, a small water-soluble iron-sulfur protein. When NADP+ and a suitable enzyme are present, two ferredoxin molecules, carrying one electron each, transfer two electrons to NADP+, which picks up a proton (i.e., a hydrogen ion) and becomes NADPH.
