What caused the bubbles to form when you added the catalase to the hydrogen peroxide and water mixture at 40 °c?

caused the bubbles to form when catalase is added to the hydrogen peroxide and water mixture at .

Further explanation:

Catalyst:

These are the substances that change the rate of a chemical reaction but these don’t get consumed in the reaction. These have wide applications in petroleum, fertilizer and pharmaceutical industries. These are also used in the formation of many substances such as ammonia, nitric acid, and sulphuric acid.

Enzymes are biological catalysts that increase the rate of chemical reactions. These are highly specific in nature. Most enzymes are proteins. These increase the rate of reaction by decreasing the activation energy. Catalase is a common enzyme that catalyzes the decomposition of hydrogen peroxide to water and oxygen.

The given reaction occurs as follows:

Here, catalase catalyzes the decomposition of hydrogen peroxide and result in the formation of water and oxygen. Bubbles are formed due to production of oxygen gas during the reaction.
