The Little Engine That Linked The Other Cars
a: Atp ~
b: train engine at a rail yard
What: "ATP in the chloroplast IS NOT used
to power the cell. Rather, this ATP is exclusively used to make sugar molecules. The longer the chain of sugars, the more ATP that is needed.
In a way, the chloroplast ATP is like a train engine at a rail yard,attaching individual rail cars to each other. Just as train cars will not form trains by themselves and need the engine to put a train together, sugar molecules need the energy of ATP to be turned into simple sugars, starches, and fibers."
