Açıklama
The correct answer is A. Fats, proteins, and carbohydrates.
The pancreas secretes digestive enzymes into the small intestine to break down:
- Fats: pancreatic lipase - Break down triglycerides into fatty acids and glycerol
- Proteins: pancreatic amylase, trypsin, and chymotrypsin - Break down proteins into amino acids
- Carbohydrates: pancreatic amylase - Break down carbohydrates into simple sugars
The other options are not correct:
B. Vitamins are not broken down by pancreatic enzymes, and cellulose is broken down by microbial enzymes in the large intestine.
C. Vitamins are not broken down by pancreatic enzymes.
