Question

In photosynthesis, the predominant metal present in the reaction centre of photo &#8211;system II is:a)Znb)Cuc)Mnd)FeCorrect answer is option 'C'. Can you explain this answer?

Accepted Answer

Photosystem II contains chlorophyll a, as well as up to 50% chlorophyll b. It probably evolved later as a supplement to Photo I. It is needed to capture enough energy to do the biosynthetic reactions of the dark reaction. Its reaction center is a molecule called P680 which absorbs light maximally at 680 nm.

Answer

In photosynthesis, the predominant metal present in the reaction center of photosystem II is manganese (Mn). Manganese plays a crucial role in the light-dependent reactions of photosynthesis, where it participates in the oxidation of water molecules and the release of oxygen. This process is known as the oxygen-evolving complex (OEC). The manganese ions in the OEC undergo a series of redox reactions, which facilitate the transfer of electrons during photosynthesis.

Answer

manganese(Mn)

Metals exert important functions in the chloroplast of plants, where they act as cofactors and catalysts in the photosynthetic electron transport chain. In particular, manganese (Mn) has a key function because of its indispensable role in the water-splitting reaction of photosystem II (PSII).
