Even though the steps of photosynthesis that actually produce sugar molecules are part of the carbon

fixation reactions, the light-dependent reactions are absolutely essential for sugar synthesis. Explain
the role of the light-dependent reactions in the formation of the end products of photosynthesis. What will be an ideal response?


Concepts to Consider: The light-dependent reactions produce ATP and NADPH, which are two
molecules that contain much of the original energy absorbed from the sun; it is these compounds that
supply energy to the endergonic process of carbon fixation.
