What is produced during the light-dependent reactions of photosynthesis?
Correct Answer: Oxygen and NADPH
Step 1: Light energy from the sun is absorbed by chlorophyll in the plant's chloroplasts.
Step 2: This light energy is used to split water molecules (H2O) into oxygen (O2), protons, and electrons.
Step 3: The oxygen produced is released into the atmosphere as a byproduct.
Step 4: The electrons move through a series of proteins in the thylakoid membrane, creating energy.
Step 5: This energy is used to convert NADP+ into NADPH, which is an energy carrier.
Light-dependent reactions – These are the first stage of photosynthesis where light energy is converted into chemical energy, producing oxygen and energy carriers like NADPH.
Photosynthesis – The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
