BLACKMAN en déduisit en 1905 que la photosynthèse comportait des réactions photosensibles et donc photochimiques (= réactions «claires»), et d'autre part des réactions indépendantes de la lumière, catalysées par des enzymes et donc dépendant de la température (= réactions «sombres»). 4, record 1, French, - r%C3%A9action%20claire
Record number: 1, Textual support number: 2 CONT
La photosynthèse est un phénomène très complexe qui donne lieu à divers types de réactions chimiques. Les unes sont dites claires car elles dépendent directement de la lumière et assurent les transformations proprement photochimiques; les autres, dites obscures, précèdent ou prolongent ces transformations photochimiques vers des synthèses organiques, ou la reconstitution de molécules organiques servant aux transferts d'énergie. 5, record 1, French, - r%C3%A9action%20claire
