Question

What is the relationship between oxygen and photosynthesis?

Answer 1

The process of photosynthesis produces oxygen.

Explanation:

The overall equation for photosynthesis is:
`6CO_2 + 6H_2O -> C_6H_12O_6 + 6O_2`

The oxygen created during photosynthesis is created when light energy is used to split water molecules. This is called the light reaction .

`2H_2O -> 2H_2 + O_2`

Here is a video which discusses the process of photosynthesis and shows an experiment in which the rate of oxygen production is influenced by available `CO_2` levels in water.

The glucose is formed by a separate process called the Calvin cycle.
