ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H ) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis. Two types of processes that contribute to the formation of the proton gradient are: processes that release H from compounds that contain hydrogen, and processes that transport H across the thylakoid membrane.

Complete question:

ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H+) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis.

Two types of processes that contribute to the formation of the proton gradient are:

processes that release H+ from compounds that contain hydrogen, and

processes that transport H+ across the thylakoid membrane.

Drag the labels to the appropriate locations on the diagram of the thylakoid membrane. Use only the blue labels for the blue targets, and only the pink labels for the pink targets.

Note: One blue target and one pink target should be left empty.

Explanation:

Fosforilation of ADP to ATP occurs while electrons descend through the electron chain, from photosystem II to photosystem I.

Placed in the thylakoid membrane, there are molecules and complexes that participate in light-dependent reactions. The places that occupy these molecules in the membrane make possible ATP synthesis. Protons are released into the thylakoid space when the water molecules split in photosystem II. Membranes are impermeable to protons, so they can not leave the thylakoid space, nor enter without a protein transporter. Through the membrane, there is an electrochemical gradient as additional protons are pumped from the stroma to the thylakoid space, using the released energy as electrons move along the chain. ADP phosphorylates to ATP while protons move from the thylakoid space to the stroma in favor of the electrochemical gradient, through ATP synthase. ATP synthesis occurs in the stroma.

not sure if this what   you'r looking for would be percent composition
