See if chlorophyll is involved. The first stage of photosynthesis involves light being captured by chlorophyll, which are pigment organelles located in chloroplast. Chlorophyll is what makes plants leaves green.
Observe if nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP) are the end products. The first set of reactions in photosynthesis breaks down the energy from light into these two energy-moving molecules.
Check and see if the final product is glucose (C3H6O3). The end result of photosynthesis is the sugar used to power a plant's growth. During this stage (also called the Calvin Cycle), NADPH and ATP combine with carbon dioxide (CO2) to create glucose.
