Answer:
The enzyme is<u> b. Catalase</u>
Explanation:
Catalases are ubiquitous biological catalysts or enzymes, that speed up reaction rates. Here, they mediate<u> hydrogen peroxide decomposition</u> into water and oxygen. They are essential in organisms on Earth exposed to oxygen as they protect cells from oxidative damage.
<h2>2 H2O2 -----→ 2 H2O + O2</h2>
hydrogen peroxide water + oxygen
Reactive oxygen species, or free radicals are very reactive- they can cause damage to DNA molecules, RNA and proteins, leading to cell death.
