Final answer:

Peroxisomal enzymes are involved in producing and breaking down hydrogen peroxide and include catalase, which safely converts hydrogen peroxide into water and oxygen to prevent cellular damage.

Step-by-step explanation:

The student has asked about the functions of peroxisomal enzymes. Peroxisomal enzymes are responsible for several functions within the cells, including both the production of hydrogen peroxide (H₂O₂) and its breakdown. Peroxisomes are vital for detoxifying substances, carrying out oxidation reactions to break down fatty acids and amino acids, which produce H₂O₂ as a byproduct. However, to prevent damage from the toxic hydrogen peroxide, peroxisomes contain enzymes like catalase that convert H₂O₂ into water and oxygen, thus neutralizing it. Therefore, the peroxisomal enzymes indeed produce hydrogen peroxide, break down hydrogen peroxide, and include catalase.
