Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.
What happens in PSII?
PSII is the multisubunit chloroplast membrane-associated pigment–protein complex that uses the energy of sunlight to drive the oxidation of water, evolving oxygen, donating electrons into the photosynthetic electron transfer chain, and depositing protons into the thylakoid lumen.
