Does an enzyme have many subunits that can have many polypeptides?

my teacher spoke about this but im still a litte confused. can someone give me a simple explanation?

An enzyme can consist of many polypeptides: This means, if you unfold it, you see multiple independent chains.

 

An enzyme can consist of multiple subunits: This is a functional breakdown and the structure in which it folds.

 

Both statements are completely independent from each other:

Two subunits (like to fix shapes) can be on the same polypeptide chain (= two fix shapes linked loosely via a flexible part of the same polypeptide chain).

One subunit (forming one fix shape with a certain function) can consist out of multiple polyppetide chains.
