Example

The enzyme was regulated allosterically by the presence of a specific molecule.

Conversation

Did you know that some enzymes can be regulated allosterically?

Yeah, I read about that! It's pretty fascinating how they work.

Right? It allows them to change their activity without direct binding.

Exactly! It’s like they have a hidden control system.

Root Explanation

Allosterically → It is formed from "allo-" (from Greek "allos", meaning other) and "stereos" (meaning solid or three-dimensional) combined with the suffix "-ically" (meaning in a manner). The term refers to the manner in which a molecule interacts with another at a site other than the active site, thus affecting its function.

Memory Tip

Think of 'other' ('allo-') and 'three-dimensional' ('stereos') to remember that 'allosterically' describes how something interacts in a different way than expected.
