The purpose of photosynthesis is to produce usable chemical energy or glucose from solar energy. if the formula for glucose is c6h12o6, how many atoms of carbon are used to produce the glucose?

If the formula for glucose is C6H12O6,  Six number of carbon atom will used to produce a glucose.

Equation:

6CO2 + 6H2O + light energy = C6H12O6 + 6O2.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
