Light energy is transferred to a chlorophyll reaction center where electrons become energized.
- A protein in the electron transport chain, pumps H+ ions from the stroma into the thylakoid space
- Electrons from the electron transport chain close to photosystem II replace the elctrons lost in photosystem I
- Electrons from Photosystem I become energized and escape photosystem I and move down the second electron transport chain.
- H+ ions flow down the concentration gradient through a channel in ATP Synthase, releasing energy in the process
- Electrons move down the electron transport chain, releasing energy
- Electrons move to an electron acceptor in the electron transport chain and electrons in photosystem II are replaced by the splitting of a water molecule
- Photosystem II receives photons in the form of light energy
- Water is split to replace the electrons in photosystem II
- At the end of the electron transport chain, the energized electrons and an H+ ion are used to reduce NADP+ to NADPH
- ATP uses energy to add a phosphate to ADP forming ATP

The answer to this question is "fluid mosaic model". We are being asked the question above and the complete sentence is below:
The contemporary description of the membrane structure of a cell is commonly known as the FLUID MOSAIC MODEL.
