Which of the following best lists the end products of the light-dependent reactions of photosynthesis?

• A. Glucose, NADPH, and O\(_2\)
• B. ATP, NADPH, and O\(_2\)
• C. Glucose, ATP, and CO\(_2\)
• D. NADH, FADH\(_2\), and O\(_2\)

Answer: (B)

Verified step by step guidance

1. Understand that the light-dependent reactions of photosynthesis occur in the thylakoid membranes of chloroplasts and are responsible for converting light energy into chemical energy.
2. Recall that the primary products of the light-dependent reactions are ATP (energy currency), NADPH (electron carrier), and O\(_2\) (a byproduct of water splitting).
3. Eliminate incorrect options by identifying that glucose and CO\(_2\) are not direct products of the light-dependent reactions. Glucose is produced in the Calvin cycle (light-independent reactions), and CO\(_2\) is a reactant in the Calvin cycle, not a product.
4. Recognize that NADH and FADH\(_2\) are electron carriers used in cellular respiration, not photosynthesis, so any option listing them is incorrect.
5. Conclude that the correct answer is ATP, NADPH, and O\(_2\), as these are the direct end products of the light-dependent reactions of photosynthesis.
