3 stages of calvin cycle?

Question

and explain

Answer 1

The calvin cycle occurs in photosynthesis. Carbon enters in the form of CO2 and exits as PGAL, which is the first stable carbohydrate created in photosynthesis. This is also called carbon fixation.

CO2 enters calvin cycle and is attached to a 5-carbon sugar RuBP. This forms a molecule with 6 carbons, which is unstable, so it breaks down to form 2 molecules (3 carbons each) of 3-PGA.

The Calvin cycle depends on the products of the light reactions. It doesn't need direct light, but it only occurs in the light.

I hope that this helps.

Answer 2

CO2 incorporation
C reduction
Regeneration of RuBP
