G3P as the Calvin Cycle's Export
Captions available
The idea
Glyceraldehyde-3-phosphate, G3P, is the Calvin cycle's exported product, a three-carbon sugar the cell converts into glucose or other organic molecules outside the chloroplast.
In practice
Combining two G3P molecules, each from a separate completed run of six cycle turns, builds one six-carbon glucose molecule.
Where people slip
G3P itself is not glucose — it is the three-carbon building block glucose and other sugars are later assembled from.
