How does the lock & key model explain an enzyme?

One enzyme works with only 1 specific substrate based on its fit

Enzymes ________ up reactions

Speed

Where do enzymes and substrates bond?

Active site

An enzyme is reusable.

True

Usually ends in -ase

Enzymes

active site

region on enzyme into which substrate fits

What does it mean when an enzyme is denatured?

That the shape is changed of the active site & it no longer works
