Question

how many water molecules are used in photosynthesis ​

Answer 1

Answer:

6 water water molecules

Overall equation for photosynthesis

For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose.

Answer 2

Answer:

6 water water molecules

Overall equation for photosynthesis

For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose.

Explanation:

In photosynthesis:

6CO2 (carbon dioxide) + 6H2O (water) + light energy -> C6H12O6 (glucose) + 6O2 (oxygen)

In respiration:

C6H12O6 (glucose) + 6O2 (oxygen) -> 6CO2 (carbon dioxide) + 6H2O (water) + cellular energy
