Chlorophyll reaction center
WebThe reaction center contains a pair of chlorophyll a molecules with a special property. Those two chlorophylls can undergo oxidation upon excitation; they can actually give up an electron in a process called a photoact. It is at this step in the reaction center, this step in photosynthesis, that light energy is converted into an excited electron. WebThe production of one molecule of O2 during photosynthesis requires how many chlorophyll molecules? thousands In the reaction center of a photosystem, which of the following excited subatomic particles are transferred to an acceptor? electrons Almost all photosynthetic organisms capture light using ______. photosystems
