Photosynthesis McKenzie gamradt

Photosynthesis is the process of plants turning sunlight into food. This process takes place in the plant leaves, more specifically, in the chloroplast inside each cell. There are two main phases of photosynthesis, light reactions and The Calvin Cycle.

Photosynthesis begins with phase one, light reactions. During this, the electron goes through the electron transport chain. The first thing that will happen is the electron will enter the chain.
Next the electron will enter photosystem II. During this, chlorophll absorbs the suns light energy and the electron gets excited.

As the electron continues to move through the electron transport chain, it starts to lose energy. When this happens, the electron enters photosystem I.

In photosystem I, the electron gets hit by the suns light and gets re-energized. Then NADP+ and H+ combine to form NADPH. This then enters the Calvin Cycle.
While that is going on, an electron enters ATP synthase. This process turns ADP and P into ATP, which is also needed for the Calvin Cycle.
The Calvin Cycle is the last part of photosynthesis. It takes the ATP and NADPH and turns it into sugars like glucose, fructose, and starch.
