independent:pH value
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.
