What is the main purpose of the light reactions in photosynthesis?
Correct Answer: To convert solar energy into chemical energy (ATP and NADPH)
- Step 1: Understand that photosynthesis happens in plants and uses sunlight.
- Step 2: Know that there are two main parts of photosynthesis: light reactions and dark reactions.
- Step 3: Focus on the light reactions, which occur in the thylakoid membranes of chloroplasts.
- Step 4: Realize that the light reactions capture sunlight and use it to energize molecules.
- Step 5: Learn that the energy from sunlight is used to create two important energy-carrying molecules: ATP and NADPH.
- Step 6: Conclude that the main purpose of the light reactions is to convert solar energy into chemical energy (ATP and NADPH) for the plant to use.
