Background Information
Photosynthesis is one of the most important processes because humans and plants depend on it. The use of light energy from the sun allows both plants and humans to get energy and food. The process of photosynthesis produces glucose and oxygen. The light reactions of photosynthesis occur in the granum. Oxygen is produced from when light strikes water and splits it into protons and oxygen. The oxygen is vital for humans since we use it in cellular respiration. Glucose is made when light strikes the chlorophyll in photosystem II, which is located on the membrane surrounding the lumen. The electrons in photosystem II are excited and go into an electron transport chain, those electrons are replaced by the electrons from the splitting of water. As they move towards a proton pump, the electrons release energy in the form of protons. The accumulated protons then move through a proton pump and into the lumen. Next, light strikes photosystem I and the electrons are exited and move into an electron transport chain. The electrons lost from photosystem I are then replaced by the electrons from the electron transport chain. Next, the electron transport chain moves to enzyme reductase, which is where the electrons from the electron transport chain are added to NADP+. By adding electrons to NADP+, NADPH is created. Because there is a large amount of protons in the lumen, chemiosmosis occurs and they move into ATP Synthase. In ATP Synthase ADP and a inorganic phosphate are joined to create ATP. The ATP and NADPH are then used in the dark reactions or calvin cycle to create glucose. The glucose the plant creates is then used for cellular respiration.
