📐 Formula — The overall reaction of photosynthesis is .
📌 The light reactions produce ATP and NADPH, whereas the light-independent reactions, called the Calvin cycle, use them to make sugar by fixing carbon.
Sunlight → chemical energy → sugar

1. What is the primary purpose of photosynthesis?
2. Which equation correctly represents the overall reaction of photosynthesis?
3. A plant cell has generated ATP and NADPH using light energy. What role do these molecules play next in photosynthesis?
What is photosynthesis?
The synthesis of sugars from CO2, H2O, and light converting light energy into chemical energy.
What is the overall chemical equation of photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2.
What do the light reactions produce in photosynthesis?
ATP and NADPH.
What is the Calvin cycle in photosynthesis?
The light-independent reactions that use ATP and NADPH to fix carbon into sugar.
Where does photosynthesis take place in plant cells?
In the chloroplast.
How many membranes surround a chloroplast?
Two membranes.
