Front

What is photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and the Calvin Cycle.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, to drive the photosynthesis process.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH provides the reducing power (electrons) needed for the Calvin Cycle.
