How does the carbon atom move from photosynthesis to cellular respiration? This has to do with Transition.

http://upload.wikimedia.org/wikipedia/commons/thumb/2/27/Calvin-cycle3.png/699px-Calvin-cycle3.png the pentose ribulose phosphate is activated by a phosphate group fixing the carbon from CO2 in the air. This reaction is catalized with rubisco enzyme.

The G-3-Phosphate molecule is then used in Krebs cycle, for cellular respiration. But i don't know how is the transition made. Most likely is with protein receptors. G3P is expelled to outside of chloroplast, so the mechanism to go from cytoplasm to mitochondria must be the same as in animal cell, when glucose comes from the blood to inside the cell.

the carbon atom in CO2 ends in a glucose molecule, 6 CO2 end up in 1 glucose molecule, and this one ends in the cell's cytoplasm. there's no difference between it coming from photosynthesis in plants, or blood in animals. It will enter mithocondria, to be used in cellular respiration. I just don't know how that molecule travels. i thought that were your question as well.
