actually the first hexose is not glucose it is fructose with a phosphate attached(fructose-6-phosphate)

Don't evrsimplify things: after glucose is created at the end, either sucrose is created in the cytoplasm for circulation and other cells or starch is created in the chloroplast for local deposits. The 2 processes are competeing with each other and the side the reation occurs depends on the local concentration of trisophosphates(hope i got the translation right..)
