Photosynthesis is the process where energy from light is used to break apart strong bonds in H2O molecules.
It involves the reduction of CO2 to carbohydrates.
The hydrogen is combined with CO2 to form glucose and O2 is released into the atmosphere.
The hydrogen comes from the photolysis of H2O.
The energy for photolysis is at first trapped by a pigment molecule called chlorophyll.
This process happens 3x, to produce C6H12O6, glucose.
Therefore, photosynthesis stores energy in glucose.
The process occurs in 2 linked stages called the light-dependent and light-independent reactions
Key Words
Phosphorylation - adding phosphate to a molecule
Photophosphorylation - adding phosphate to a molecule using light
Photolysis - the splitting of a molecules using light energy
Hydrolysis - the splitting of a molecule using water
Redox Reactions - reactions that involves oxidation and reduction; the oxidation of 1 molecule always involves the reduction of another, and vice versa
