Questions & Step-by-Step Solutions

Which enzyme is responsible for breaking down hydrogen peroxide in cells?
  • Step 1: Understand what hydrogen peroxide is. It is a chemical compound (H2O2) that can be harmful to cells.
  • Step 2: Learn that enzymes are proteins that help speed up chemical reactions in the body.
  • Step 3: Identify the specific enzyme that helps break down hydrogen peroxide. This enzyme is called catalase.
  • Step 4: Know the function of catalase. It converts hydrogen peroxide into two harmless substances: water (H2O) and oxygen (O2).
  • Step 5: Remember that this process is important for protecting cells from damage caused by hydrogen peroxide.
