Verified step by step guidance

Understand the role of intestinal enzymes: Intestinal enzymes are responsible for breaking down nutrients in the small intestine. They help in the digestion of carbohydrates, proteins, and fats.

Identify the enzymes listed: Maltase, Sucrase, and Lactase are enzymes that function in the small intestine. They are involved in the breakdown of carbohydrates.

Recognize the function of each enzyme: Maltase breaks down maltose into glucose, Sucrase breaks down sucrose into glucose and fructose, and Lactase breaks down lactose into glucose and galactose.

Consider the role of Pepsin: Pepsin is an enzyme that breaks down proteins into peptides. It is active in the stomach, not the intestine.

Determine which enzyme is not an intestinal enzyme: Since Pepsin functions in the stomach, it is not an intestinal enzyme, unlike Maltase, Sucrase, and Lactase.
