Question: 1 / 400

Which enzyme, produced in the pancreas, is responsible for digesting fat?

Amylase

Lipase

Lipase is the enzyme produced in the pancreas that is specifically responsible for the digestion of fats. This enzyme catalyzes the breakdown of triglycerides, which are the main constituents of body fat in humans and other animals, into free fatty acids and glycerol. The action of lipase occurs primarily in the small intestine, where it is secreted in an active form and then works in conjunction with bile salts to emulsify fats, making them more accessible for digestion.

Amylase, on the other hand, is responsible for breaking down carbohydrates; it acts on starches and glycogen. Pepsidase is involved in protein digestion, specifically breaking down peptides into amino acids, while protease also functions to digest proteins but does not target fats. Therefore, the function of lipase is distinct and crucial to the metabolic processing of dietary lipids.
