What structure within a cell contains enzymes to get rid toxic substances like hydrogen peroxide?

Peroxisome

What is the relationship between an apoenzyme, a cofactor, and a holoenzyme?

The apoenzyme binds to the cofactor to form the active holoenzyme.

Where do enzyme competitive inhibitors bind?

The active site

Where do enzyme non-competitive inhibitors bind?

On the enzyme, but not the active site
