Question
Chlorophylls absorb light energy, which is converted into chemical energy through the formation of two compounds, ATP— an energy storage molecule, and NADPH— a reduced (electron-bearing) electron carrier. State true or false.
- True
- False
Hint:
Light energy is converted into chemical energy in photosynthesis
The correct answer is: True
- In light department reactions the energy from the sunlight is absorbed by a chlorophyll
- This light energy is converted into chemical energy
- This chemical energy is stored in the form of ATP and NADPH
- Light energy is used to split water producing oxygen and electrons that produces ATP and NADPH
