Enzyme regulation confusion/question- help appreciated

[Incis0r]

What's the difference between allosteric inhibition and noncompetitive inhibition?

According to Cliffs, an "allosteric inhibitor binds to the enzyme and induce the enzyme's inactive form." On the same page however, it is written that "In noncompetitive inhibition, a substance inhibits the action of an enzyme by binding to the enzyme and t a location other than the active site. The inhibitor changes the shape of the enzyme which disables its enzymatic activity."

I'm confused- doesn't an allosteric inhibitor also bind to a site other than the active site (it binds to the allosteric site)? So how would I separate allosteric inhibition from noncompetitive inhibition?

Please help! Thank you.

Thank you Feralis I tried looking for a similar thread but my keywords were "enzyme regulation confusion" so I unfortunately did not find your thread previously. This helps a lot. I appreciate it!

You are spot on. It's in the Chemistry chapter (chapter 1) of Cliffs AP Bio

No biochem. Really simple chemistry stuff is tested because it's such an important component of biology in general. It's just like... a chapter in Cliffs
