In the thylakoid between photosystem II and photosystem I.
between phoyosystem I and II
Photosynthesis happens, most of the time, in the organelle called the chloroplast. However, there are organisms that have other types of plastids that can also carry out photosynthesis. Cyanobacteria perform photosynthesis on their plasma membranes. Essentially, photosynthesis can happen in a variety of locations. All it needs is some membrane materials to make a chemiosmotic gradient as well as the proteins to catalyze the reactions.
The chemiosmotic production of ATP through photophosphorylation in photosynthesis is closely related to the chemiosmotic production of ATP through oxidative phosphorylation in cellular respiration. Both processes utilize a proton gradient across a membrane to power the ATP synthase which phosphorylates ADP into ATP.
Chemiosmotic phosphorylation
Recductive phosphorylation is the opposite of oxidative phosphoroylation. Reductive phosphorylation will occur in photosynthesis, when the chemiosmotic gradient is created because proteins along the thylakoid membrane have channeled hydrogen ions from the stroma to the thylakoid space. After, the hydrogen ions want to go back into the stroma because of the chemiosmotic gradient, and therefore, the enzyme ATP Synthase will open and let them run through. Like a wind turbine, it will spin at the same time, and crush ADP and P to make adenosine triphosphate (ATP). This whole process as a whole is called reductive phosphorylation because it essentially is one of the steps in reducing (giving electrons) carbon dioxide to glucose.
Chemiosmotic generation of ATP is driven by a gradient of H+ ions (protons). These protons move from high to low concentration, and in the process, power a protein that phosphorylates ADP into ATP.
Diffusion of ion molecules accross a permeable membrane
Main fuel is glucose. It is oxidized using oxygen
Because the unique structure of the cell wall forms a plate during mitosis and the chloroplast help with photosynthesis, a process that has certain differences with respiration.. i.e Chemiosmotic synthesis of ATP and the such..
oxidative phosphorylation does not involve with the respiratory complex in the inner mitochondria membrane. Oxidative phosphorylation useful in generate the production of ATP from the proton gradient or proton motive force. Chemiosmotic coupling invilve the manner of ETC on how its create the proton gradient and the proton gradient is indirectly directed with the production of ATP.The proton gradient causes the conformational change of tigthly binding of ATP to open binding ATP .Then ATP can be released and be used to the metabolic cell needs and translocate the ATP to cytoplasm that can be used to phosphorylate substrate.

The membrane inside the thylakoid of the chloroplast pumps H+ ions from the outside compartment (stroma) to the inside (lumen). This builds the gradient. The electrons are pumped using energy released from a high energy electron which was energized through light absorption. This electron comes from the breakdown of water.
Of course it has chloroplasts.They are well developed plants.

The light dependent reactions take place in the thylakoid of the chloroplast. ATP is formed in the ATP synthase protein by the assistance of the hydrogen gradient produced in the electron transport chain.
The chemiosmotic hypothesis claims electron transport chains generate ATP indirectly, by the creation of a proton-motive force.
