Question

What is the significance of photolysis of water in photophosphorylation? What happens to each product of this process?​

Answer 1

$\huge\mathfrak{\bf{\underline{\underline{\blue{Answer \ :}}}}}$

• Photolysis of water in the presence of sunlight is the breakdown of the water molecule into hydrogen and oxygen.

• During the first photosynthesis step, ps-II (p680) absorbs the light energy.

• The chlorophyll electrons are energized to the excited state and absorbed by the electron acceptor.
