where does the energy used to establish the proton gradient across the thylakoid membrane come from?
In other words, from splitting of water. well that's not what he said but there you go.

The "photo" part of that word refers to light. You can get that light from a light bulb but the be all end all source of light on this planet is what? The sun, right? Right.

What uses energy from the high-energy electrons to transport hydrogen across the thylakoid membrane?
Electron transport chain
What is the role if ATP synthase in photosynthesis?
The pigment molecules and electron transport chains involved in the light-dependent reactions of photosynthesis are embedded in the thylakoid membrane. As energy is released from electrons traveling through the chain of acceptors, it is used to pump protons (that is, H+ ions) from the stroma of the chloroplast across the thylakoid membrane and into the center of the thylakoid. Thus, protons accumlate within the thylakoids, lowering the pH of the thylakoid interior and making it more acidic. A proton gradient possesses potential energy that can be used to form ATP.Protons are prevented from diffusing out of the thylakoid because the thylakoid membrane is impermeable to protons except at certain points bridged by an enzyme called ATP synthase. This protein extends across the thylakoid membrane and forms a channel through which protons can leave the thylakoid. As the protons pass through ATP synthetase, energy is released, and this energy is tapped by ATP synthase to form ATP from ADP and inorganic phosphate. The coupling of ATP synthesis to a protein gradient formed by energy released during electron transport is called chemiosmosis.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.
Where does the energy to move hydrogen ions across the thylakoids membrane come from?
Concentration gradient is made first.Solar energy is used.
How do the two photosystems work together to capture energy from sunlight?
Photosystem 2 transports the electrons from water and oxygen and Hydrogen ions across the Thylakoid membrane. Photosystem 1 produces NADPH with the electrons being added to NADP. ADP is changed to ATP when the Hydrogen ions flow through ATP synthase. I hope this helps! :)

Electron transport chain
Energy used to establish the protein gradient across the thylakoid membrane comes from where?
Synthesis of ATP
What releases energy that is used to pump hydrogen ions from the stroma into the thylakoid compartment?
The electron transport chain releases energy in order to pump protons (hydrogen ions) from the stroma into the thylakoid compartment, creating a proton gradient within the thylakoid membrane.
Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane results in the synthesis of ATP during light reaction. Thylakoid membranes contain proteins. These proteins make use of light energy to drive electron transport chains. This generates a chemiosmotic potential across the thylakoid membrane and NADPH. The ATP synthase enzyme uses the chemiosmotic potential to make ATP during photo- phosphorylation.

They are embedded in the thylakoid membrane in the chloroplasts :-)
