What types of nutrients does pancreatic juice help to digest?

1. Proteins

2. Carbohydrates

3. Fats

4. All of the above

The correct answer is: All of the above

Pancreatic juice is a crucial digestive fluid produced by the pancreas, and it plays a significant role in the digestion of all three macronutrients: proteins, carbohydrates, and fats. The composition of pancreatic juice includes a variety of enzymes that specifically target these nutrients. For proteins, the juice contains proteolytic enzymes like trypsin and chymotrypsin, which break down proteins into smaller peptides and amino acids. For carbohydrates, the enzyme amylase in pancreatic juice helps to convert complex carbohydrates into simple sugars. Lastly, for fats, the juice includes lipase, which is responsible for breaking down triglycerides into fatty acids and glycerol. Since pancreatic juice contains these essential enzymes that aid in the digestion of proteins, carbohydrates, and fats, it is accurate to say that it helps to digest all of the above nutrients. This multifunctional aspect of pancreatic juice highlights its importance in the digestive process, allowing for the efficient breakdown and absorption of vital nutrients necessary for the body's metabolic needs.
