Q: Is photosynthesis exergonic

Flexi Says:

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.
