The pD1 is processed to mature D1 by carboxyl-terminal peptidase A to remove the C-terminal extension and form active protein. Here we report functional characterization of the Arabidopsis gene encoding D1 C-terminal processing The function of photosystem II is electron transfer. Photosystem II splits water molecules and transfers electrons as it's primary function. Conclusion: The light reactions convert solar energy to chemical energy (ATP and NADH). This reduces the power of sugar synthesizing in the Calvin Cycle. Photosystem 1 Electron Transport Chain What's going on in Photosystem 1?

Photosystem 1 function

2019-03-19 2016-09-16 Photosystem I, a membrane protein complex found in all oxygenic photosynthetic organisms, uses light energy to transfer electrons from plastocyanin to ferredoxin. Light energy captured by antenna chlorophylls is transferred rapidly to the primary electron donor, P 700. 2020-06-02 Until now, the functional and structural characterization of monomeric photosystem 1 (PS1) complexes from Thermosynechococcus elongatus has been hampered by the lack of a fully intact PS1 preparation; for this reason, the three-dimensional crystal structure at 2.5 Å resolution was determined with the trimeric PS1 complex [Jordan, P., et al. (2001) Nature 411 (6840), 909−917]. Main Function.

From:Postharvest Physiology and Biochemistry of Fruits and Vegetables, 2019 The primary function of the photosystem I in NADPH synthesis, where it receives the electrons from PS II, and the photosystem II is in the hydrolysis of water and ATP synthesis.

Photosystem I, a membrane protein complex found in all oxygenic photosynthetic organisms, uses light energy to transfer electrons from plastocyanin to ferredoxin. Light energy captured by antenna chlorophylls is transferred rapidly to the primary electron donor, P 700.

As before, the electron that is excited in Photosystem I needs to be replaced, or the system will eventually run out of electrons and come to a stop. There is a second function for the electron Photosystem II (PSII) reaction center protein D1 is synthesized as a precursor (pD1) with a short C-terminal extension. The pD1 is processed to mature D1 by carboxyl-terminal peptidase A to remove the C-terminal extension and form active protein.

Abstract. The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed. Photosystem I, a membrane protein complex found in all oxygenic photosynthetic organisms, uses light energy to transfer electrons from plastocyanin to ferredoxin. Light energy captured by antenna chlorophylls is transferred rapidly to the primary electron donor, P 700. Function i Possible role could be the docking of the LHC I antenna complex to the core complex.
