Plastocyanin, Ferredoxin, and Ferredoxin NADP+ Oxidoreductase (Photosynthesis Part 5)

The video tutorial explains the process of electron transfer in Photosystem 1, focusing on the roles of P700, plastocyanin, and ferredoxin. It describes how light energy is absorbed by antenna molecules and transferred to P700, which then donates electrons through a series of acceptors, including phylloquinone and iron-sulfur centers, ultimately reaching ferredoxin. The tutorial also covers the regeneration of P700 by plastocyanin and the function of ferredoxin-NADP+ reductase in producing NADPH.

How does the reduction of phylloquinone occur in the electron transfer process?

What happens to P700 after it donates an electron to a sub zero?

Describe the final steps of electron transfer from ferredoxin to NADP+.
