PS 1 is located on the non- pressed surfaces of the thyllakoid in the choloroplast
Photosystems I and II are both in the thylakoid membranes of the chloroplast.
A Photosystem is a funnel shaped cluster of photosynthetic pigments, in the thylakoid membrane of the chloroplast.
The cooperation of the two photosystems of the chloroplast is required for the efficient generation of ATP and reducing power (NADPH) during photosynthesis. Photosystem II captures light energy to drive the electron transport chain, while photosystem I helps in the production of NADPH by receiving electrons from photosystem II. This cooperation is essential for the overall functioning of the light-dependent reactions in the chloroplast.
The chemiosmotic gradient is developed across the thylakoid membrane of the chloroplast. This is achieved through the transfer of protons from the stroma to the thylakoid lumen during the light-dependent reactions of photosynthesis.

NADPH
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
Photosystem 2 is located in the thylakoid membrane of the chloroplasts, while Photosystem 1 is located downstream from Photosystem 2 in the thylakoid membrane. Both photosystems are important for light-dependent reactions during photosynthesis.
Light energy is not exactly trapped. The light energy excites the electron in the reaction centres of photosystem I and photosystem II. The electron excites and transfers to the electron transport chain ( chain of electron carriers), this produces ATP. Then the electron of photosystem II is transferred by photosystem I and the electron of the photosystem I is used with H+ and NADP to form NADPH. Photosystem II gets back an electron from photolysis of water.
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis
Photosystem 1
No, carbon dioxide is not a direct output of Photosystem II in photosynthesis. Photosystem II's primary function is to harvest light energy and use it to split water molecules into oxygen, protons, and electrons. Carbon dioxide is utilized in the Calvin cycle, which occurs in a different part of the chloroplast.
