Question

As electrons travel from the primary electron acceptor in photosystem II, down the electron transport chain to photosystem I, they drive the movement of protons from the stroma into the thylakoid compartment. Why is the development of this chemical gradient useful to photosynthesis?

Answer 1

Is important because thethylakoid compartment needs protons to hydrolize water and ATP needed for photsynthesis.

Step-by-step explanation:

There two photosystem (I and II) each of them is needed in order to manatain a balanced and welldone photosynthesis.

In photosystem I is made the NADPH synthesis, which can be done by the electrons received from PS II. On the other hand, the photosystem II its main function is to hidrolize the ATP and water.

Both systems need from one to other because if photosystem II doesn´t give the electrons to photosystem I, photosynthesis won´t develop in a correct way.

It is important since the correct light absorption of the plant until the correct process of photosynthesis.
