CO₂

The oxygen molecule in glucose formed during photosynthesis comes from carbon dioxide. It comes from the splitting of water during the light-dependent reaction. Whereas glucose is formed from CO₂ and hydrogen released from water.

$6 C O_{2} + 12 H_{2} O s u n l i g h t, c h l o r o p h y l l \to C_{6} H_{12} O_{6} + 6 O_{2} + 6 H_{2} O$
