Question

Why does the x mean in the word equation for photosynthesis

Answer 1

The ''x'' in the word equation for photosynthesis is ATP

Explanation:

$6 CO_2 + 12 H_2O + photons \rightarrow C_6H_1_2O_6 + 6O_2 + 6 H_2O.$

Oxygen + glucose carbon dioxide + water + x

A chemical reaction happens in this photosynthesis where the atom arrangements are changed to different arrangement to form a new substance.  When during the time of photosynthesis, the energy from the Sun is stored in the form of chemical energy.

Here the X is ATP, the Adenosine triphosphate which provides energy for the plants. ATP releases small amount of energy through hydrolysis.
