The organ that produces enzymes that break down fats, proteins, and carbohydrates is the pancreas.

Here's a breakdown:

* Pancreatic enzymes: The pancreas produces a variety of digestive enzymes, including:

* Lipase: Breaks down fats into fatty acids and glycerol.

* Protease: Breaks down proteins into amino acids.

* Amylase: Breaks down carbohydrates (starches) into sugars.

These enzymes are released into the small intestine, where they mix with food and help digest it.
