…These assimilation pigment molecules are thought to assemble into functional units. It is estimated that there is one reaction center chlorophyll molecule for about 300 chlorophyll molecules, and such a set is called a photosynthetic unit. There are two types of photosynthetic units: those belonging to photosystem I (PSI), in which the reaction is mainly driven by light absorbed by chlorophyll a, and those belonging to photosystem II (PSII), in which the reaction is mainly driven by light absorbed by accessory pigments. … *Some of the terminology that refers to "photosynthetic unit" is listed below.

…これらの同化色素分子は,集合して機能的な単位体を作っていると考えられている。クロロフィル約300分子に対し,反応中心のクロロフィル分子が1個あると推定されており,このような1組を光合成単位photosynthetic unitという。光合成単位としては,主としてクロロフィルaに吸収される光によって反応が行われる光化学系I(PSI)に属するものと,主として補助色素に吸収される光によって反応が行われる光化学系II(PSII)に属するものとの2種がある。… ※「photosynthetic unit」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
