Question

Order the steps through which atp synthesis occurs during the light-dependent reactions of photosynthesis in plants

Answer 1

At the same time, the electron transport chain produces ATP. (This is why the the process is called oxidative phosphorylation.) ... This creates a concentration gradient of protons that another protein complex, called ATP synthase, uses to power synthesis of the energy carrier molecule ATP.
The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). The products of this reaction are sugar molecules and other organic molecules necessary for cell function and metabolism. Note that the dark reaction takes place in the stroma (aqueous fluid surrounding the stacks of thylakoids) and the cytoplasm.

Answer 2

The light dependant phase of the photosynthesis uses light for producing two molecules which are required for the next stage of the photosynthesis process. In plants the light dependant phase take part in Thylakoids. Photosystems are obtimised to use the correct amount of light plays a very important role in photosynthesis. There are two types of photosystems - PS1 and PS2
