Photosynthesis The thing that i need to understand to pass this class please mr ellens go easy

Photosynthesis is used by plants, and algae and normally occurs in the leaves. This is where the materials needed for photosynthesis are found.
A photon created by the fusion reactions of the sun gets absorbed by chlorophyll. When chlorophyll gets hit by that photon, an electron absorbs that energy and gets excited.
The electron will now begin its journey to extract all of the new found energy in order to put it towards something useful to the cell. This is known as the electron transport chain. The electron then has so much energy that is goes to a special protein meant for stealing electrons. The protein is called a mobile electron carrier.
The Chlorophyll then splits the stable molecule H2O in in order to steal its electron to regain the one it lost. The bi products of this reaction are hydrogen and oxygen. This reaction is what releases oxygen and allows us to breath.
The cytochrome complex uses a small amount of the electrons energy to put another protein in its thylacoid. The thylacoid is then getting filled with protons. The protons repel each other so they push their way through the enzyme strataling the thylacoid membrane called ATP synthase. That enzyme uses the energy to pack an ionic phosphate into ADP making atp the main form of cellular energy.
The electron now enters photostyem one. After a couple of photons excite a couple of more electrons, the electrons then go to another electron carrier. All of this energy is then used to make NADPH which like ATP are used to carry energy around. Here another enzyme helps combine two electrons and one hydrogen ion with something called NADP+.
Now is when the calvin cycle begins. Or light independent reactions. The calvin cylce begins in the stroma. This next faze is called carbon fixation. CO2 is fixed RUBP with the help from an enzyme known as rubisco. This causes the carbon chain to become unstable. The only way to regain stability to break apart creating 3 molecules of phosphiglirate
ATP puts some phosphate group onto the phosphoglyrate and then ADPH adds some electrons. This creates 2 molecules of Glyceroldehyel 3 phosphate. This is a high energy compound that plants can convert into almost any carbohydrate. For example glucose for short term storage and starch for long term storage.
