Question
_________ is the first step of the Calvin pathway.
- Carbon dioxide fixation
- Regeneration
- Synthesis of sugar
- Reduction
Hint:
The Calvin cycle, light-independent reactions, the organic synthetic phase, dark reactions, or the photosynthesis carbon reduction cycle is a chemical reaction that turns carbon dioxide and other compounds into glucose. these are the chemical reactions.
The correct answer is: Carbon dioxide fixation
Carbon dioxide fixation is the first step of the Calvin pathway.
Calvin cycle begins with the reaction of CO2 with highly reactive phosphorylated five carbon-sugar named ribulose bisphosphate.
