Q:

Which of the following equations represents Photosynthesis?

A) 6CO2 + 6H2O -----> C6H12O6 + 6O2 B) C6H12O6 + 6O2 -----> CO2 + 6H2O
C) CO2 + H2O -----> C6H12O6 + 6O2 D) 6O2 + 6H2O -----> C6H12O6 + 6CO2
 
Answer & Explanation Answer: A) 6CO2 + 6H2O -----> C6H12O6 + 6O2

Explanation:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms activities.

 

Photosynthesis can be represented using a chemical equation.

 

The overall balanced equation is

 

              6CO2 +  6H2O   Sunlight    C6H12O6   +   6O2Source of Carbon & Oxygen  + Source of Electrons & Hydrogen + Energy that drives Photosynthesis             ----> Sugar + Gas produced by splitting water.

 

Where 

CO2 = carbon dioxide 

H2O = water

C6H12O6 = glucose 

O2 = oxygen.
