b) H2O → P680 chlorophyll a pair → PS II primary electron acceptor → Pq → cytochrome complex → Pc → P700 chlorophyll a pair → PS I primary electron acceptor → Fd → NADPH
Explanation:
The energy present in the photons is used to produce high energy electrons during the light chain of reactions. The H2O molecules generate P680 which is an excited chlorophyll molecule. Then the molecules are converted into pheophytin. The pheophytin produce special quinones which are QA and QB. This generates a plastoquinone pool.
Lavoisier’s oxygen theory of combustion was one of his most
notable contribution to science and earned him the title of the “father of
modern chemistry”. He recognized the combustible property of oxygen and that phosphorus and other metallic elements increased in terms of weight when burned.
