One product of photosynthesis is glucose (sugar), which provides the basis for most food chains. The second product of photosynthesis is oxygen which comes in handy if your happen to be an aerobic organism that requires oxygen for survival.
Photosynthesis is one of the more unusual endothermic reactions, but it certainly is one. The basic formula for photosynthesis is this: 6CO2+6H2O â C6H12O6 + 6O2. During photosynthesis, the plant absorbs energy from sunlight, which helps it produce glucose and oxygen from the initial reactants, carbon dioxide and water.
