Answer:
Sugar and oxygen.
Explanation:
Sugar is the main product of Calvin cycle while oxygen is the by product of the process.
The sugar is obtained as 6-C compounds by reduction of Cabondioxide with Hydrogen ions obtained from the photolysis of water, in the light dependent stage. Thus the production Sugar takes place in the light -independent state.
The Oxygen is produced during photolysis splitting of water to H+ + e- + O- at the light dependent stage. This is the basic reaction of Light dependent stage.
The Hyrogen is used for CO2 as mentioned above , while the O2 liberated for cellular respiration as by product.
