Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions ... that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. ... P700 receives energy from antenna molecules and uses the energy from each photon to raise an electron to a higher energy level ... In one model, Fx passes an electron to Fa, which passes it on to Fb to reach the ferredoxin. Ferredoxin (Fd) is a soluble ...
Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions ... The function of the light-dependent reaction is to convert light energy into chemical energy within a multi-protein complex ... that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. ... Light energy (indicated by wavy arrows) absorbed by photosystem II causes the formation of high-energy electrons, which are ...
Significantly, we show that the energetic requirements for producing oil and starch relative to the recoverable energy stored ... the dominant energy storage products in Chlorophytic microalgae. We discuss how thermodynamic restrictions including the loss ... conversion of solar into chemical energy achieved. In this review, we examine the thermodynamic and kinetic constraints ... Regardless, overall biological energy capture, conversion, and storage in microalgae are inefficient with less than 8% ...
