Comment what I should make next. ----------------------------------------------------------------------------- LIGHT REACTIONS STEP-BY-STEP H2O is absorbed by the plant and brought through the chloroplast into the thylakoid lumen, where it is the broken down into O2 and H, the H is turned into H+ by removing an electron, this is important for later. The electron then goes into photo-system II (even though its the first one in the process) The electron loses its power and needs to be recharged. Light shines onto the plant and photons from the light are absorbed by the P680 which is then used to charge the electron. The electron proceeds to exit photo-system II and make its way to photo-system I, along the way, it releases H+ atoms to the other side of the cell wall however, the H+ atoms want to go back to the other side, so they have to passes the ATP synthase which uses ADP (Adenosine diphosphate),and Pi (isoelectric point) to create ATP (Adenosine triphosphate) which stores energy and fuels the plant. Meanwhile electrons run out of energy again, so they stop at the photo-system I to gain back its energy. After doing so the electron gets picked up by NADP+ which is then turned into NADPH (Nicotinamide adenine dinucleotide phosphate) and brought over to the calvin cycle. Obviously, some things are inaccurate that I will fix, some other time when I learn my lesson on procrastinating, like NADPH instead of NAPDH, (I still do bitmap typos like a loser.) and p700 instead of p680 on photosystem 1, and hydrogen going the wrong way when the electron is powering up in Photosystem 1, and the list could go on. If you find any other mistakes I made, make sure to correct me in the comments below. WOW! that was a lot, i'm all out of breath! Make sure to hit the heart and star for more science animations like this one.
