Photosynthesis: Light Reactions and the Calvin Cycle

The video explains photosynthesis, a process by which plants convert sunlight, water, and carbon dioxide into energy. It covers the two main stages: light reactions and the Calvin cycle. Light reactions occur in chloroplasts, producing ATP and NADPH, while the Calvin cycle synthesizes organic molecules. The video also highlights the role of chlorophyll in absorbing sunlight and the importance of photosynthesis in the food chain.

How do light reactions contribute to the process of photosynthesis?

What is the significance of ATP and NADPH in the Calvin cycle?

Explain the difference between the light reactions and the Calvin cycle.
