Raw materials required for photosynthesis are water and Carbondioxide. The end products of photosynthesis are glucose and oxygen.
Evolution of Oxygen during photosynthesis
Photosynthesis includes a series of chemical reactions. They are light phase (photochemical phase) and dark phase (synthetic biophase).
The light phase is also known as the light-dependent phase because it occurs only in the presence of light. It occurs in the granum of the chloroplast.
The light phase of photosynthesis includes three steps:
Step 1: Chlorophyll molecules get activated by absorbing sunlight.
Step 2: The water molecule splits to form Hydrogen and Hydroxyl ions. During this process, oxygen is released.
Step 3: ATP and NADPH are formed. These are known as the assimilatory power of photosynthesis.
Both photosystem 1 and photosystem 2 involve the light phase.
The electrons removed from photosystem 2 during noncyclic photophosphorylation must be replaced.
This occurs due to electrons available due to the splitting of water molecules.
The protons and oxygen are released within the lumen of the thylakoid.
