What large group of biomolecules does catalase belong to?

1 Answer

Answer:

Catalase is a protein.

Explanation:

Catalase is an enzyme, which are biological molecules that catalyze chemical reactions that take place in biological systems.

In fact, catalase is one of the most efficient enzymes that operate inside a cell. Its function is to catalyze the decomposition of hydrogen peroxide, #H_2O_2#, which has a toxic effect on the cell, into water and oxygen.

Adding catalase to a beaker that contains hydrogen peroxide will accelerate its decomposition.

See this reaction by watching the video below. The wood splint bursting into flames verifies that the decomposition of #H_2O_2# forms oxygen gas.
