Answer:
C. The light-independent reactions
Step-by-step explanation:
Photosynthesis consists of two phases: light dependent phase and light independent phase.
a) The light dependent phase of photosynthesis includes photolysis of water, release of oxygen and synthesis of ATP and NADPH.
b) Light independent phase of the photosynthesis includes chemical pathway to fix atmospheric carbon dioxide into glucose. Since this chemical pathway was first discovered by Calvin, it is called as Calvin cycle.
