Catalase primarily breaks down a single substrate: hydrogen peroxide (H₂O₂). It catalyzes the decomposition of hydrogen peroxide into water (H₂O) and oxygen (O₂). While catalase is specialized for this reaction, it does not act on multiple substrates in the way that some other enzymes might. Therefore, it is accurate to say that catalase predominantly has one main substrate.
The enzyme catalase breaks down how many different substrates?
