Reaksi Terang Fotosintesis

Hello, peace be upon you, meet me again with Widyaningsih, this time we will discuss the material about the light reaction of photosynthesis, pay attention, photosynthesis comes from the word photo which means light, so making food using sunlight, the reaction is CO2 DIY adds H2O with sunlight energy to become oxygen and glucose, it turns out that

this reaction consists of two major reactions, the first is the light reaction or photolysis of water and the second is the dark reaction or Kelvin cycle or CO2 fixation, we discuss one by one, yes, the place where photosynthesis occurs is in the chloroplast, let's see the picture, yes, there is an outer membrane, an inner membrane, then there are

thylakoids like plates, what is green, stacked, that is where the light reaction or photolysis of water occurs, while the stroma or liquid is where the dark reaction or CO2 fixation occurs, we discuss the light reaction, yes, the light reaction or photolysis of water, lysis means broken, while photo is light, so water photolysis is the reaction of

breaking down water using sunlight energy, the place is in the chloroplast, some grana or thylakoids, Well, we can see in the picture, yes, it turns out it's complicated too Here is the light reaction there is photosystem 1 photosystem 2 cyclic and noncyclic typical of which is oxygen 2 nadph2 and 2atp we will discuss one by one yes The first

is photophosphorylation or cyclic reaction namely the formation of ATP by photosystem 1 well photosystem 1 we call it p700 because it captures sunlight with a wavelength of 762 meters we see the mechanism yes based on the picture p700 absorbs light with a wavelength of 762 meters then the captured electrons will go to the primary acceptor then
