Photosynthesis is when plants use sunlight to make food out of carbon dioxide and water.
The sun comes down and autotrophs absorb the light to make food. Chlorophyll is a pigment and takes in the sun's energy, this is a light dependent reaction. It absorbs all the colors except green. Then, light will travel to the chloroplast. The reactions begin the in Thylakoid Membrane. Then the Electron Transport train starts where it pumps protons when the electrons start moving through the chain.
That's a little confusing but I think I get it.
Now starts the Calvin Cycle which takes place in the stroma and is a light independent reaction. The electrons from the Electron Transport Train go into the cycle to create ATP and Glucose. ATP gives the cell energy to keep running. The Glucose heads to the Mitochondria and when it does it gets broken down in a process called Glycolysis. Glycolysis breaks down the glucose into two pyruvic acids. These pyruvic acids go to the Krebs Cycle to make more ATP. The the Mitochondrial Electron Train starts which is similar to the last transport train with the electrons moving along and pumping protons, but this time the electrons at the end get picked up by oxygen.
