Questions & Step-by-Step Solutions
What is produced during the light reactions of photosynthesis?
Correct Answer: Oxygen and NADPH
Step 1: Understand that photosynthesis happens in two main stages: light reactions and dark reactions.
Step 2: Know that light reactions occur in the thylakoid membranes of chloroplasts when sunlight is absorbed.
Step 3: Realize that during these reactions, water (H2O) is split to release oxygen (O2).
Step 4: Learn that the energy from sunlight is used to convert ADP and NADP+ into energy carriers: ATP and NADPH.
Step 5: Conclude that the main products of the light reactions are oxygen (O2) and NADPH.
Light Reactions of Photosynthesis – The light reactions occur in the thylakoid membranes of chloroplasts, where light energy is converted into chemical energy in the form of ATP and NADPH, and oxygen is released as a byproduct.
