hormons and enzyms

[raghda]

In glucolysis and kreb's cycle insulin affects on enzyms of the cycles (inhibitory or stimulatory)
But generally, is the mechanism of hormons act through enzym not directly on certain structure (mean: enzym serve hormon)
IS THIS TRUE???????

raghda, pleeeease type whole words and not part of words, as I am not a native speaker.
Now, i don't remember exactly, but logically insulin should inhibit glycolysis. If it does, than more likely than not it inhibits phosphofructokinase.

I don't think I've understood the question. Is it just me?

hormones work through receptors (it could be intracellular or cell surface)

i agree with what was posted here.
