The oxygen produced in photosynthesis comes from what molecule?

Answer 1

From #H_2O#.

The hydrogen ions will be used by later steps of photosynthesis towards the end goal of making carbohydrates.

Here is a look at aquatic plants carrying out the light reaction, the video also gives a brief summary of photosynthesis.
