When photosystem II is being exposed to less sunlight a smaller number of electrons will be available in thylakoids.
What is Photosystem II?
- In higher plants, algae, and cyanobacteria, Photosystem II (PSII) is a membrane protein super-complex that performs the initial reaction of photosynthesis.
- It uses the sun's light to catalyze the separation of transmembrane charges.
- Water molecules are divided into hydrogen ions (H+) and oxygen atoms by Photosystem II, which obtains replacement electrons from them.
- Molecular oxygen (O2) is formed when oxygen atoms combine and are discharged into the environment. In the lumen, hydrogen ions are released.
- After the photon strikes, photosystem II delivers the liberated electron to the first of a sequence of proteins known as the electron transport chain inside the thylakoid membrane.
What are thylakoids?
- "Thylakoids are interconnected disc-like sacs of the internal membrane system of the chloroplast."
Hence, the less sunlight will result in less number of electrons in thylakoid.
