How is oxygen generated in photosynthesis?

See below.

Explanation:

The equation for photosynthesis:

6CO_2 + 6H_2O → C_6H_12O_6 +6O_2

The carbon and oxygen in $6 C {O}_{2}$ contribute to forming glucose (${C}_{6} {H}_{12} {O}_{6}$) as well as the hydrogen from the water.

The oxygen is produced from the splitting of the ${H}_{2} O$ molecule and is a waste product.
