A photosynthetic reaction center (or photosynthetic reaction center) is a complex of several proteins, pigments and other co-factors assembled together to execute the primary energy conversion reactions of photosynthesis. Molecular excitations, either originating directly from sunlight or transferred as excitation energy via light-harvesting antenna systems, give rise to electron transfer reactions along a series of protein-bound co-factors. These co-factors are light-absorbing molecules (also named chromophores orpigments) such as chlorophyll and phaeophytin, as well as quinones. The energy of thephoton is used to promote an electron to a higher molecular energy level of a pigment. The free energy created is then used to reduce a chain of nearby electron acceptors, which have subsequently higher redox-potentials. These electron transfer steps are the initial phase of a series of energy conversion reactions, ultimately resulting in the production of chemical energy during photosynthesis.
The complex of proteins and pigments assembled together to carry out the primary energy conversion reactions of photosynthesis is known as the reaction center.

the reaction center.
chlorophyll
The reaction involves the transfer of excited electrons from chlorophyll to a nearby primary electron acceptor molecule. This process is vital in photosynthesis as it initiates the flow of electrons through the electron transport chain.
The light-harvesting (or antenna) complex of plants is an array of protein and chlorophyll molecules embedded in the thylakoid membrane which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
False
The reaction center contains special chlorophyll called Chlorophyll a.

The reaction center in photosynthesis is where light energy is converted into chemical energy. It is a key part of the process that allows plants to produce glucose and oxygen using sunlight.
The group of proteins and pigments that transfers electrons to reaction center
Photosystem is composed of pigments, reaction center and electron acceptor
Yes, energized electrons at the primary electron acceptor flow to the reaction center of photosystem I or II in the process of photosynthesis. This movement of electrons is essential for the conversion of light energy into chemical energy in the form of ATP and NADPH.

The light-harvesting (or antenna) complex of plants is an array of protein and chlorophyll molecules embedded in the thylakoid membrane which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
It passes the energy to the reaction center ( a specialized region of photosystem) then the energized electrons leave the reaction centers and are passed to adjacent electron transport chains (ETC)
