What Are the Reactants in Photosynthesis?
- Photosynthesis requires carbon dioxide (CO2) and water (H2O) as reactants. The standard reaction requires six molecules of each.
- Energy from sunlight is the catalyst that drives photosynthesis. Without sunlight, photosynthesis cannot take place.
- Glucose (C6H12O6) and oxygen (O2) are released as products.
- Photosynthesis takes places in chloroplasts, which are primarily located in a plant's leaves rather than the stem.
- Photosynthesis is effectively the opposite of respiration, which requires oxygen and releases carbon dioxide. Without photosynthesis, oxygen supplies would eventually dwindle and carbon dioxide would reach problematic levels.
