Is photosystem 2 light dependent?

Yes, photosystem 2 is a light-dependent process in photosynthesis. It absorbs photons to initiate the light-dependent reactions of photosynthesis, where it helps generate oxygen and produce ATP and NADPH.


How much ATP is produced in the light dependent reactions?

In the light-dependent reactions of photosynthesis, ATP is produced through the process of photophosphorylation. Each cycle of the light-dependent reactions produces two molecules of ATP.

Through which process is oxygen produced as a byproduct?

light-dependent reaction


What is the purpose of the light dependent reaction and what is it called?

The purpose of the light dependent reaction is to convert light energy into chemical energy in the form of ATP and NADPH. This process, also known as the light reactions or light-dependent photosynthesis, occurs in the thylakoid membranes of chloroplasts.


Where do the hydrogen ions for the photosystems of the light-dependent reactions originate?

The hydrogen ions for the photosystems of the light-dependent reactions originate from water molecules during the process of photosynthesis.


What happens during the light dependent process?

plants can use energyNADP, ATP


Name two stages of photosynthesis?

There is the light-dependent stage, where sunlight interacts with choloropyll to set up an electron-transport chain, then there is the chemical stage, where glucose molecules are synthesized from CO2 and H2O.


What is the first process in the light dependent reactions of photosynthesis?

Excitation of electrons in photosystem II.
