Help on Enzymes?

Post by Vickiki » Thu Dec 01, 2011 8:12 pm

. . . I'm kind of Bio-stupid. (Sorry if it's posted in the wrong section)
We've got a test on enzymes tomorrow, so fast replies would be nice.

In my textbook, it says "Enzymes cannot catalyze reactions until the substrate binds to the active site."
I thought the active site was part of the substrate? Isn't the active site like, just where the enzymes and substrate bind?

& If I took a picture of these two paragraphs from my textbook that I'm confused about, would anyone actually translate it to something I might be able to understand?

active site is part of enzyme molecule, not of substrate. It's the place, where substrate binds into.

Cis or trans? That's what matters.
