the Soceral events occure in the chloroplost.
in this photothemsis paseo process
Answers
Answer:
Splitting of water molecules in presence of light, release protons, electrons and oxygen is called Photolysis of water.
This was first experimentally proved by Robert HIill.
It occurs in the lumen of the chloroplasts.
It is an important step in photosynthesis, because, by this step, oxygen released into the atmosphere and electrons and protons are donated to photosynthesis.
Answer:
This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll; a type of photosynthetic pigment that converts the light to chemical energy. This reacts with water (H2O) and splits the oxygen and hydrogen molecules apart.
From this dissection of water, the oxygen is released as a by-product while the reduced hydrogen acceptor makes its way to the second stage of photosynthesis, the Calvin cycle.
Overall, since the water is oxidized (hydrogen is removed) and energy is gained in photolysis which is required in the Calvin cycle
