There are some people who are not familiar with photosystem 1. This is the second photosystem that happens in the photosynthetic light reactions that are experienced by bacteria, algae, and plants. This is an important complex wherein light will have the ability to produce the needed carriers such as NADPH and ATP.
It is photosystem II that is able to produce and contain chlorophyll. If this would not occur, it will not be possible for biosynthetic reactions to occur. There is a molecule that will be produced called P680 that will have the ability to absorb the light properly.
