Photolysis reaction in grana
WebOct 23, 2024 · Stage I: Light dependent reaction/ Hill reaction: Light reaction occurs in grana of chloroplast and it requires the light for it to take place. Green plants uses light belonging to visible spectrum (380nm-760nm). In light reaction, the light energy is converted into chemical energy in the forms of ATP, NADPH+H +, and oxygen. WebSo, the grana of the chloroplast are concerned with the light reaction. 2. In second step, light is not required but the assimilatory power generated in first step used up for the fixation of C O 2 into carbohydrate. This step is called dark reaction or thermochemical reaction which takes place in the stroma of chloroplasts. 3.
