Question

The light reaction of photosynthesis does not include

Answer 1

Answer:

The correct answer will be option-C.

Explanation:

Photosynthesis is a complex process which converts light energy into chemical energy which is used to form the glucose molecule.  Photosynthesis occurs in two stages: light-dependent and light-independent reaction.

The light-dependent reaction is the reaction which takes place in the sunlight and converts light energy to chemical energy in ATP and NADPH molecules.

The light-dependent begins when photosystem absorbs light energy which causes the excitation of the electrons provided by chlorophyll molecule. The excited electrons get accepted by electron acceptor molecule and a chain of electron flow begins called electron transport chain.

This creates a scarcity of electron in photosystem which causes hydrolysis of the water molecule as a result oxygen gas is released. The electron flow leads to the synthesis of ATP molecules through chemiosmosis.  

Thus, Option-C is the correct answer.
