CO2 and H 2 0
|
|
|
CO2 AND C6H12O6
|
|
|
oxygen and water

Explanation:
Detailed explanation-1: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).
Detailed explanation-2: -The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. The single chemical equation represents the overall process of photosynthesis.
Detailed explanation-3: -For the production of one molecule of glucose, 12 NADPH molecules are required and for production of 12 NADPH molecules, 12 water molecules are required. Thus in photosynthesis, 12 molecules of water are used as a substrate.
