is photosynthesis exergonic
One of the most important series of endothermic reactions is photosynthesis. In photosynthesis, plants make the simple sugar glucose (C6H12O6) from carbon dioxide (CO2) and water (H2O). They also release oxygen (O2) in the process. The reactions of photosynthesis are summed up by this chemical equation:
- 6 CO2 + 6 H2O → C6H12O6 + 6 O2
The energy for photosynthesis comes from light. Without light energy, photosynthesis cannot occur. Plants can get the energy they need for photosynthesis from either sunlight or artificial light.
