How do you remember the photosynthesis equation?

The equation for respiration is:

C6H12O6 + O2 --ENZYMES--> CO2 + H2O + 36ATP

OR

Sugar + Oxygen --ENZYMES--> Carbon Dioxide + Water + Energy

Aerobic respiration, the production of energy with oxygen, is the opposite of photosynthesis: the reactants are the products of the other.

If you want an easier one though, one that they teach in middle school, it is just:

C6H12O6 + 6O2 ---> 6CO2 + 6H2O + E (energy)

Or - glucose + oxygen ----> carbon dioxide + water + energy
