Light-Harvesting The Antenna Complex

The video explains how light energy is transferred in photosystems, focusing on the reaction centers P680 and P700. It describes the role of the antenna complex in transferring energy to the reaction center, emphasizing the unidirectional and efficient nature of this process. The video also highlights the spontaneous nature of energy transfer from high to low energy states, facilitated by the antenna complex, and introduces the concept of Gibbs free energy in this context.
