Question

Which component of air is used up during photo synthesis?

Answer 1

Carbon dioxide

Explanation:

Photosynthesis is a process where plants make food (sugars like glucose) and oxygen gas from raw materials, such as carbon dioxide and water.

The full balanced chemical equation of photosynthesis is:

`6CO_2(g)+6H_2O(l)stackrel"light"stackrel"chlorophyll"->C_6H_12O_6(aq)+6O_2(g)`

The glucose is then broken down into pyruvate, which is then further broken down into `ATP`, the molecular currency of energy.

But from the air, photosynthesis only needs carbon dioxide from it, and sunlight if you count it as well.
