Question 2

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?
