Verified step by step guidance

Step 1: Understand the definition of an enzyme. Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process. They are typically proteins.

Step 2: Analyze the given compounds. Trypsin, Amylase, and DNA polymerase are all enzymes. Trypsin is a protease that breaks down proteins, Amylase catalyzes the breakdown of starch into sugars, and DNA polymerase is involved in DNA replication.

Step 3: Consider Hemoglobin. Hemoglobin is a protein found in red blood cells responsible for transporting oxygen throughout the body. It does not catalyze any chemical reactions, so it is not classified as an enzyme.

Step 4: Compare the roles of enzymes and non-enzyme proteins. Enzymes facilitate biochemical reactions, while non-enzyme proteins like Hemoglobin perform other functions such as transport, structural support, or signaling.

Step 5: Conclude that Hemoglobin is the correct answer because it is not an enzyme, unlike the other compounds listed.
