The first step for initiation of photosynthesis will be:
| 1. | Photolysis of water |
| 2. | Excitement of chlorophyll molecule due to absorption of light |
| 3. | ATP formation |
| 4. | Glucose formation |
What happens in light reaction (Photo chemical reaction):
| 1. | Formation of ATP and NADPH2 |
| 2. | Formation of ATP |
| 3. | Formation of sugar |
| 4. | Breakdown of sugar |
