The bubbles could be viewed as a sign that the peroxide is "eating" the bacteria. You will notice after a while that fewer and fewer bubbles appear, that is because the bacteria is getting killed.
The enzyme is catalase. It can exist without adding hydrogen peroxide. The hydrogen peroxide simply activates the enzyme.
Catalase, however it does not produce hydrogen peroxide but rather catalyzes the breakdown of hydrogen peroxide into water and oxygen gas.
The hydrogen peroxide is both oxidized and reduced, to produce water and elemental oxygen.
When Hydrogen Peroxide (H2O2) is heated, it produces water (H2O) and Oxygen (O2). The chemical reaction is: 2 H2O2 + heat ---> 2 H2O + O2
You think probable to acetone. The acetone peroxide is an explosive.

Water
Because your blood contains an enzyme called peroxidase that explicitly exists for the purpose of catalyzing the decomposition of peroxides.

No, it means the peroxide is decomposing. You see this when you pour hydrogen peroxide into a wound because your body naturally produces a protein called peroxidase that catalyzes the decomposition of peroxides. This is why small amounts of hydrogen peroxide don't kill you: your body has a natural mechanism for dealing with it. Bacteria, for the most part, do not produce peroxidase, so they're highly susceptible to the effects of peroxides.

2H2 + O2 -> 2H2O - reaction to produce water H2+O2-> H2O2 - reaction to produce hydrogen peroxide
Colourless, oxygen is produce by the catalytic action of the Iron in the liver on the hydrogen peroxide. 2 H2O2 -> 2 H2O + O2.

Hydrogen peroxide is a toxic substance that is sometimes made in our cells due to some chemical reactions. It is poisonous so cells produce an enzyme called 'Catalase' which break down hydrogen peroxide to water and oxygen. Because catalase is in our blood, if hydrogen peroxide is added to it, it breaks down: Blood + H2 O2(hydrogen peroxide) --changes to-- H2O (water) + O2 (oxygen).
