Verified step by step guidance

Understand the role of the small intestine and pancreas in digestion. The small intestine is where most of the digestion and absorption of nutrients occurs, while the pancreas secretes enzymes that aid in digestion.

Identify the types of enzymes secreted by the pancreas. The pancreas produces several key enzymes: amylase for carbohydrates, lipase for fats, and proteases for proteins.

Recognize the function of these enzymes. Amylase breaks down carbohydrates into simple sugars, lipase breaks down fats into fatty acids and glycerol, and proteases break down proteins into amino acids.

Consider the role of the small intestine. The small intestine also produces enzymes that continue the digestion process, working alongside pancreatic enzymes to ensure complete breakdown of nutrients.

Conclude that the primary function of these enzymes is to aid in the digestion of proteins, carbohydrates, and fats, ensuring that nutrients are broken down into their simplest forms for absorption.
