In non-cyclic reactions of photosynthesis, electrons from chlorophyll molecules in photosystem-I are used in the formation of NADPH. What is the source of such electrons?
1 Light
2 NADPH
3 Photosystem-I
4 Photosystem-II, which is related to splitting of water molecule
Explanation:
In non-cyclic reaction of photosynthesis, electrons from chlorophyll molecules in photosystem I are used in the formation of NADPH. The source of those electrons is photosystem II which splits water molecule.

Cyclic phosphorylation results in the formation of
1 NADPH
2 ATP and NADPH
3 ATP, NADPH and \({O_2}\)
4 ATP
Explanation:
During cyclic photophosphorylation only one photosystem is involved, P700. When the photons activate, a pair of electrons are raised to a higher energy level and captured by the electron acceptors. At each electron transfer proton gradient is established which is responsible for formation of ATP.

Which of the following is operational during cyclic photophosphorylation?
1 Only PS II
2 Only PS I
3 Both
4 Only PS III
