NEET BIOLOGY

Detailed explanation-1: -The electron will be passed on through the first leg of the photosynthetic electron transport chain in a series of redox, or electron transfer, reactions.

Detailed explanation-2: -After the photon hits, photosystem II transfers the free electron to the first in a series of proteins inside the thylakoid membrane called the electron transport chain.

Detailed explanation-3: -During the light-dependent reaction, photosystem II is the first to capture light energy, followed by photosystem I. The reason why photosystem II goes before photosystem I have something to do with their evolution. It is believed that photosystem II evolved first than photosystem I.

Detailed explanation-4: -Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis.

Detailed explanation-5: -Photosystem II (PSII) is a membrane protein supercomplex that executes the initial reaction of photosynthesis in higher plants, algae, and cyanobacteria. It captures the light from the sun to catalyze a transmembrane charge separation.
