Reaksi Gelap Fotosintesis ( Fiksasi CO2 / Siklus Calvin)

Hi Hi assalamualaikum warahmatullahi wabarakatuh meet me again with me Widyaningsih continuing the previous video this time we will discuss the dark reaction of photosynthesis pay close attention, okay Well photosynthesis like the previous video we have discussed the light reaction of photosynthesis this time we will discuss the dark reaction of photosynthesis, namely the CO2 fixation reaction

binding CO2 into C6 h12 o6 or what we call the Kelvin cycle where the dark reaction of photosynthesis occurs is in the chloroplast stroma or chloroplast fluid touching the dark reaction because it is called a dark reaction because it does not require sunlight Then it is called CO2 fixation because it binds carbon dioxide and is

also called the Kelvin cycle Well we want to talk about the mechanism of the Kelvin cycle, yes, the first 6 CO2 is bound by six rubp ribulose diphosphate will become phosphoglyceric acid or 12 abg or vegal then using the energy produced by the light reaction, namely ATP and nadph bg ga will be converted

into phosphoglyceraldehyde or 12v gael next using STP 12 Vega R will be changed two Vega l into glucose and 10 begalnya into rubp again and return to the initial stage then we call it the Kelvin cycle well the conclusion of the dark reaction of photosynthesis this time is the photosynthesis reaction where CO2 plus

H2O becomes oxygen and C6 h12 o6 it turns out there is a second process that is the dark reaction because it does not require light then CO2 fixation is carried out by Heru bpq Kelvin cycle using ATP and nadph the result of the light cycle the result is glucose or carbohydrates we discuss the question yes photosystems
