Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis?

The light-dependent reactions use light energy to split water, producing oxygen and storing energy in ATP and NADPH. The light-independent reactions (Calvin cycle) use ATP and NADPH to fix carbon dioxide into sugars. Thus, the correct choice is “The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH, and CO₂.”
