Solution
The structure you're referring to is the reaction-center complex. Here's the step-by-step process:
- Light energy is absorbed by the chlorophyll in the reaction-center complex of the photosystem.
- This energy excites an electron in the chlorophyll, causing it to be at a higher energy level.
- The excited electron is then transferred to the primary electron acceptor.
- The primary electron acceptor then passes the electron to an electron transport chain, where it will go through a series of redox reactions to ultimately produce ATP and NADPH.
