Answer:
The correct answer will be option-D.
Explanation:
Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.
The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy. This absorption causes the excitation of the electrons provided by the chlorophyll molecule.
The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.
This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.
Thus, option-D is the correct answer.
A light reaction is a photosynthetic reaction that converts light into chemical energy. It includes ETC, splitting of water and formation of the ion gradient.
What is the light reaction?
A light reaction is a photosynthetic reaction that uses light energy to convert carbon dioxide and water molecules into chemical energy in the form of glucose and oxygen.
The light-dependent photosynthetic reaction occurs in the chlorophyll of the cells after the absorption of the photons and the excitement of the electrons of the ETC.
The scarcity of electrons leads to the spitting of the water by hydrolysis and releases the oxygen molecule.
For the formation of the ATP molecule, a gradient of the hydrogen ions is created across the membranes and results in the acceptance and donation of the electron in the membrane.
Therefore, option. d. all of the above are correct.
