The Calvin cycle, also known as the C3 cycle or the light-independent reaction, is a crucial biochemical pathway in photosynthesis that occurs in the stroma of chloroplasts. It is responsible for the fixation of atmospheric carbon dioxide (CO₂) into organic molecules, ultimately leading to glucose synthesis. The Calvin cycle consists of three main stages: Carbon Fixation, Reduction, and Regeneration of RuBP (Ribulose-1,5-bisphosphate).

1. Carbon Fixation:

  • The enzyme Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) catalyzes the first step of the cycle.
  • CO₂ (1 molecule) from the atmosphere is fixed by RuBP (5-carbon compound) _______ _____ __________ ________ ______ ______ ____ ___ ____.
