Exploring the Process of Photosynthesis

The video tutorial explains the process of photosynthesis, where plants use sunlight, water, and carbon dioxide to produce carbohydrates and oxygen. It details the two main stages: light reactions in the thylakoid, which generate ATP and NADPH, and the Calvin cycle in the stroma, which uses these molecules to convert carbon dioxide into carbohydrates. The tutorial also highlights the role of chloroplasts and provides a chemical formula for photosynthesis.

What is the chemical formula for photosynthesis?

• Solar energy + 6 H2O + 6 O2 -> C6H12O6 + 6 CO2

• Solar energy + 6 CO2 + 6 H2O -> C6H12O6 + 6 O2
