Photosynthesis consists of two primary steps: **light reactions** and the **Calvin cycle** (also known as the dark reactions). Therefore, the correct answer from your options is **A: light reactions in Calvin cycle**.

- **Light reactions**: These occur in the thylakoid membranes of the chloroplasts and convert light energy into chemical energy (ATP and NADPH).
- **Calvin cycle**: This takes place in the stroma of the chloroplasts and uses the ATP and NADPH produced in the light reactions to fix carbon dioxide and produce glucose.
