Answer:
6 turns
Step-by-step explanation:
The right question goes like this, "The Calvin cycle is a 3-stage cycle. How many turns it takes to make one molecule of the glucose."
The detailed answer to this is,
Three turns of the Calvin cycle are needed to create one molecule of G3P that exit the cycle and go towards the making of glucose.
G3P is a 3-Carbon molecule that contains three fixed atoms of carbon, so it takes two molecules of G3P to build a six-carbon molecule of glucose. Therefore, we can conclude that it would take six turns of the Calvin cycle or six molecules of carbon dioxide, eighteen ATP, and twelve NADPH to produce one glucose molecule.
