An Overview of Calvin Cycle - Stages Of C3 Cycle

C3 cycle refers to the dark reaction of photosynthesis. It is indirectly dependent on light and the essential energy carriers are products of light-dependent reactions. In the first stage of the Calvin cycle, the light-independent reactions are initiated and carbon dioxide is fixed. In the second stage of the C3 cycle, ATP and NADPH reduce 3PGA ...
