Verified step by step guidance

Understand that enzymes are biological catalysts that speed up chemical reactions in the body, and each enzyme is specific to a particular substrate or type of reaction.

Identify the function of each enzyme listed: Amylase breaks down carbohydrates, Lipase breaks down fats, and Lactase breaks down lactose, a sugar found in milk.

Recognize that Pepsin is an enzyme that specifically digests proteins. It is produced in the stomach and works optimally in the acidic environment there.

Recall that protein digestion begins in the stomach, where pepsin breaks down proteins into smaller peptides.

Conclude that among the options given, Pepsin is the enzyme responsible for protein digestion, as it is the only one that acts on proteins.
