What goes into the photosystems and what comes out of the systems. where will these products go?

The various photosystems depend on the sunlight to prepare food. These photosystems are known as the autotrophs. The unicellular autotrophs like the cynobactera have the chlorophyll pigment in their body. This pigment absorbs the energy from the sunlight to cause a reaction between the absorbed carbon dioxide and water to form glucose and oxygen. Oxygen gets released into the atmosphere as a byproduct of the reaction. In cynobacteria there is no defined place for the storage of glucose. But in higher multi-cellular organisms like plants, the storage happens in the stalk of the leaves.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
