What stages of the light-dependent reactions occur prior to the buildup of hydrogen ions in the thylakoid compartment? Select all that apply.     Energy emitted by the electron transport chain triggered by PSII generates a hydrogen ion gradient across the thylakoid membrane.   PSII pulls replacement electrons from water molecules, which then break apart into oxygen atoms and hydrogen ions.   A photosystem II (PSII) absorbs light energy and releases an electron.   Electrons released from PSII enter an electron transport chain in the thylakoid membrane.   A flow of hydrogen ions causes ATP synthase to phosphorylate ATP.

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.
