Which of the following statements is true with regard to the light reaction of photosynthetic mechanism in plants ?
Which of the following statements is true with regard to the light reaction of photosynthetic mechanism in plants ?
The correct option is D Photosystem I and photosystem II are both involved in non-cyclic photophosphorylation.
A. Chlorophyll a occurs with peak absorption at 700 nm in PS I and 680 nm in PS II.
B. Mn and Cl− are associated with photolysis of water.
C. No O2 is evolved during cyclic photophosphorylation
D. In non electron
transport process the excited electron from PS II is accepted by primary
acceptor quinone, which sends them to an electron transport system consisting
of plastoquinone, cytochrome complex and plastocyanin.The excited electron absorbed by PS I reaction
center, then transfer to the ferredoxin(Fe), then the reduced Ferredoxin
donates the electron to NADP+.
So, the correct answer is 'PS I and PS II are both involved in non- cyclic photophosphorylation'.
