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.

∙ 10y agoInto the thylakoid? Or into the thylakoid space (also known as the thylakoid lumen)? That energy originally comes from the sun. We're talking photosynthesis, right? 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?
The protein complex ATP synthase uses the energy from high-energy electrons to transport hydrogen ions across the thylakoid membrane during the process of photosynthesis. This creates a proton gradient that drives the production of ATP, which is an important energy carrier in the cell.
Is chlorophyll found in the thylakoid membrane or in the thylakoid space?
Chlorophyll is found in the thylakoid membrane of chloroplasts. It is a pigment that plays a crucial role in absorbing light energy during photosynthesis.
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.
Where is the site of the photosystems in the light-dependent reactions of photosynthesis?
The photosystems in the light-dependent reactions of photosynthesis are located in the thylakoid membranes of the chloroplast. Photosystem I and Photosystem II are embedded in the thylakoid membrane and are responsible for capturing and converting light energy into chemical energy.
What happens to electrons in the thylakoid membrane?
they return to their original energy levels.

Chemiosmosis in the thylakoid membrane is directly responsible for?
Chemiosmosis in the thylakoid membrane is directly responsible for the generation of ATP during photosynthesis. It involves the movement of protons across the thylakoid membrane to create a proton gradient, which drives the synthesis of ATP by ATP synthase enzyme.

Synthesis of ATP

What releases energy that is used to pump hydrogen ions from the stroma into the thylakoid compartment?
The flow of electrons through the photosystems during photosynthesis releases energy that is used to pump hydrogen ions from the stroma into the thylakoid compartment. This process is driven by the transfer of energy-rich electrons from photosystem II to photosystem I, creating a proton gradient that is essential for ATP production in the light reactions of photosynthesis.
The carrier protein that transports hydrogen ions across thylakoid membranes and produce ATP acts as both?
The carrier protein that transports hydrogen ions across thylakoid membranes and produces ATP acts as both a pump and an enzyme. It uses the energy from the movement of hydrogen ions to generate ATP through chemiosmosis.

When the ATP synthesis molecules are open the hydrogen ions move out of the thylakoid. how does the cell use the kinetic energy of the moving ions?
The movement of hydrogen ions creates a concentration gradient and charge difference across the thylakoid membrane. As the ions flow back into the stroma through ATP synthase channels, their kinetic energy is harnessed to convert ADP and inorganic phosphate into ATP, the universal energy carrier molecule in cells. This process is known as chemiosmosis and is essential for ATP production during photosynthesis.
