One molecule of catalase can catalyze the decomposition of millions of hydrogen peroxide molecules per second. It is estimated that a single catalase enzyme can perform around 40 million reactions per minute, effectively breaking down hydrogen peroxide into water and oxygen. This high turnover rate showcases its efficiency as a biocatalyst in protecting cells from oxidative damage.

How many monomers are present in a molecule of catalase?

Catalase is an enzyme composed of four identical monomer subunits, making it a tetramer. Each monomer is a polypeptide chain that contributes to the enzyme's overall structure and function. Thus, there are four monomers present in a single molecule of catalase.


How often can a catalase molecule be used to hydrolyze hydrogen peroxide?

A catalase molecule can be used multiple times to hydrolyze hydrogen peroxide. It speeds up the reaction without being consumed in the process, allowing it to catalyze the decomposition of many molecules of hydrogen peroxide before being reused.

What effect does catalase have on the breakdown of hydrogen peroxide?

Catalase, an enzyme found in many living organisms, accelerates the breakdown of hydrogen peroxide into water and oxygen. It does this by lowering the activation energy required for the reaction, making the process faster. This decomposition of hydrogen peroxide into water and oxygen helps protect cells from damage caused by this reactive molecule.

What are the properties and functions of the hoh molecule in chemical reactions?

The H2O molecule, also known as water, has unique properties that make it essential for chemical reactions. It is a polar molecule, meaning it has a positive and negative end, allowing it to dissolve many substances. Water also has a high specific heat capacity, which helps regulate temperature changes in reactions. Additionally, water can act as a solvent, participate in acid-base reactions, and facilitate biological processes.
