Calvin Cycle order:
Step 1: Carbon fixation
Step 2: Reduction
Step 3: Release of G3P
Step 4: Regeneration
Explanation:
The Calvin Cycle is a part of the photosynthesis process where carbon dioxide from the air is converted to glucose by autotrophs.
Calvin Cycle is constituted by a set of redox reactions that are light independent. Calvin cycle takes place in the stroma of the chloroplast. This process was discovered by Melvin Calvin by tracing carbon atoms during carbon fixation in photosynthesis.
Carbon fixation: In this step, a carbon dioxide molecule will combine with ribulose-1, 5 phosphate (five-carbon) molecule to form a six-carbon (6-C) compound. This 6-C compound will further divide to form two 3-carbon compound (3-PGA).
Reduction: ATP along with NADPH convert or reduce the 3-C compound (3-PGA) to 3-C sugar (G3P)
Release of G3P: A part of G3P molecules gets converted to glucose
Regeneration: Remaining G3P molecules are recycled to regenerate the compound RuBP acceptor which will initiate the next cycle.
