WebMay 25, 2024 · Antenna complex is an array of proteins and chlorophyll b molecules that transfers light energy to the reaction center of a photosystem, while the reaction center is a complex of several proteins, pigments, and co-factors that execute the primary energy conversion reaction of photosynthesis. WebThe reaction center of a photosystem contains a unique pair of chlorophyll a molecules, often called special pair (actual scientific name—that's how special it is!). Once …

WebDRAW a curved arrow mechanism for photosynthesis with the following steps. Show the flow of electrons in the drawing. 1: Absorption of sunlight and excitation of chlorophyll molecules. 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. 3: Electron transfer from oxidized chlorophylls to an electron The reaction center contains two pigments that serve to collect and transfer the energy from photon absorption: BChl and Bph. BChl roughly resembles the chlorophyll molecule found in green plants, but, due to minor structural differences, its peak absorption wavelength is shifted into the infrared, with … See more A photosynthetic reaction center is a complex of several proteins, pigments and other co-factors that together execute the primary energy conversion reactions of photosynthesis.
