Name an oxidoreductase enzyme.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of an oxidoreductase enzyme. Oxidoreductases are a class of enzymes that facilitate oxidation-reduction reactions, which involve the transfer of electrons between molecules.

2. **Identifying an Example**: One well-known example of an oxidoreductase enzyme is glucose oxidase.

3. **Function of Glucose Oxidase**: Glucose oxidase catalyzes the oxidation of glucose to glucono delta-lactone. This reaction uses molecular oxygen as an electron acceptor.
